A lot of units in the game have amazing animations, especially when it comes to chaining/overall damaging skills (Ellesperis for example, with the blood particles), but there is a big downside with how the game works : all the numbers (damage, chains, but also healing and shields) are on top of everything else. I think adding an option to be able to remove those numbers would be a great improvement because we all would be able to enjoy our favourite units' animations to the fullest, and we now have the chain and damage recap at the end of every turn so we can still keep track of that.

I have no idea if it is actually possible to implement that in the game, but if it is, it would be amazing.
