Battle Pass, in-game store, always online, slow and buggy AI, and some other minor complaints make this a downgrade from 2.

The battle-passes would be fine if they just added cosmetics, but they have teams locked behind them. When my friend tried this he wasn't sure where to get teams that were only available in battle-passes before. I haven't opened up the shop and won't. I would buy DLC from Steam, but really don't care for the way this game has been monetized. Make it free to play if you want it to be structured this way.

I really like turn-based games for being able to stop and start as I need, in 2 I save and quit games often and really assumed that I could do that again. The first time I tried to do it in 3, I was dumbfounded - I could only concede.

Some of the graphics are improved, but the UI is a bit busy and not helpful. In particular there are some in-game elements that are hard to read, like the radial wheel and the block options. The main menu is also frustrating to navigate, a lot of the options and choices are not intuitive or explained.

They are beta-testing the eternal league right now and that could add some reason for me to come back, but once I'm finished with the "campaign" I will stick with 2 when I want to play.

Aggressive micro-transactions, every customization option and teams. I understand needing to continue making money on a game but damn make it cheaper at least.

8 bucks to get a team, if you want a chunk of custom stuff for the team at a discount, its 20 bucks, if bought separate looking at 50 bucks. Times this by 8 at time of this review and you are looking at around 50 bucks to get all the current teams or 160 bucks to get teams and SOME custom items not all.

At least they did make it so custom equips are unlocked and not single use anymore unless its a legendary one. Also going offline makes it so nothing you have done or unlocked is usable.

Visually it looks nice but even on a discount be warned that the game has MANY problems.
Visual and gameplay bugs still occur with models displaced to several squares from where they actually stand, having to make rolls against opponents that are not there are a few examples.
At the very least you can level up and acquire teams and rewards just by playing the game so at least you don't have to pay real money for all cosmetics and teams, however it can take time but still nice to at least have the ability to get around paying for these additions.
Honestly you would have to be truly blinded by either buyers remorse, being a die hard fan or actively being deceptive to recommend this game with out any warning about the problems it still has.
Got this on sale so not as bad for me personally, only paying a small amount for it, would suggest anyone else do the same if you are really interested.
