So I've been playing DLS20 since a bit after launch and I've actually enjoyed it more than DLS2019. I totally understand why some people would be upset over the move to the new app or the removal of offline career mode plays but I won't delve into that because it doesn't affect me too much. Regardless, here's some of my thoughts on it:
+ A new font is used, a much less crude one and is easier on the eyes and fits with the aesthetic more than DLS19's one, so that's a plus.
+ The graphics got revamped with heavier bloom and heavier shadings. My opinion is very subjective on this change but I think it's a big improvement in terms of graphics.
+ Many gameplay aspects were improved and is more realistic. The main thing being the raised difficulty. The DLS20 AI's ability to keep the ball can be really impressive, as opposed to DLS19 where it's laughably easy to regain possession.
+ The AI can now score some good goals (long shots, team goals, etc...) so there's a visible difference in the AI's offensive capabilities compared to DLS19 (Although I could be wrong on this one, it could just be that the improvements in pass accuracy and ball control allowed them to create more chances).
+ The new Free Kick layout is a huge improvement, so that if you're careful enough, even low overall players can have a chance of scoring FKs, unlike DLS19 where even 80-85 Shooting players will have difficulty landing a shot on target from a FK.
+ The new Transfer mechanic is more realistic, and makes the career mode have a build-up feel to it (And not just saving up money to buy one of the world-class players readily available after each match to then end up with a completely unrealistically inconsistent team). The Transfer Window, however, has problems which I'll talk about later.
+ Manager customization is one of the neat added details that I really appreciate.
+ Events are now much more rewarding, and I love it. One of the best changes so far.
o The gem system is something I'll also not delve into, since it's a Free to play game, they need an IAP purchasable currency so the low gain rate is understandable. However, it's commendable that the game still throws you a bone compared to other free games, when the gem gaining rate is not quite as unforgiving. You also don't need fully upgraded facilities to have a comfortable experience, so it's just a nice bonus for people who have money to spend.
- The new Player Development system is something I'm having very mixed thoughts about. Right now, when all of my players can benefit from an improvement one way or another, there's not many problems with it, yet I think it would be a much more serious problem late-game when you focus on building the team that you want instead of climbing the ranks. Being unable to develop players that you'd like to due to pure luck is a bad thing. (Especially if a very expensive Legendary Coach can have a chance to be wasted on a maxed out player).
- The player search system is gone, and I don't understand why. It's an useful system when you wanted to see if your favorite players are in the game, what position is their main one, what are their stats/overall, etc... even when they're not available for transfer.
- The new Transfer system is reduced to 9 players at a time, or 11 if you use a Scout (Which right now is pretty useless, and I'll talk about that), which is WAY too low. The old game has over 80 available transfers at a time, which is understandably a lot. But constricting it to 9 makes it incredibly hopeless if you want to buy a specific players. This is especially bad late-game, when your team overall is at 80 or higher. You'd have immense trouble waiting to scout out a youngster from your favorite team or a low-overall player that you'd like to have and develop when everyone on the windows is at least 69-70 overall and half of them are Rares and Legendaries. In DLS19, where there's about 80 players available after each game, you still had to wait for like a dozen matches for one specific player to be available because of how many players there are. I'd imagine there's even more players in DLS20, which will make the whole process even more hellish. What I'd suggest is to gradually expand the number of players available in the Window as your team improves. It's also more realistic that way too, since big teams have no problems signing lesser known players.
- The Scouting system is nigh useless. You'd think that for something you have to spend your currency on, you'd at least be able to choose which position you wanted to scout or so, but no. Just 2 random players, with a progressing chance of getting Rares or Legendaries. If you don't find the correct players to fill the position you need improvement in from those 2 out of probably a thousand or so players? Too bad. I've never used it early to mid game, and late game, my only purpose for it is to look for specific players that I want with lower overalls, and even THEN it's not doing its job efffectively, since I have no ability to narrow down my search, which is something scouts are supposed to do. I just want Scouts to have the ability to look for specific positions, that would make them a lot better and much more useful.
- Custom Players are gone. Yeah this one's a bummer for me. Custom Players is, to me, the best feature DLS19 offered that made it stood out from other football games. It makes everyone's teams have a personal feel to it and makes you more attached to your efforts. I really hope they bring it back, it's one of the biggest incentives for me to stay with DLS for as long as I did.
- When you get a Red Card, you cannot change the position of the player who got sent off to replace their position with someone else. So if you're playing 3 at the back and a defender gets red carded, you're playing with 2 at the back for the rest of the game.
- The announcer counts deflections as "headers". It's been like that since DLS2019 and is not really all that impactful so it's technically fine if it's not fixed.
- Deflected passes sometimes accelerates the ball to a crazy speed. This bug doesn't happen too much, though and it's pretty funny.
