Just making this topic on a whim, basically everyone knows it's beta and everyone knows it's their chance to change what they don't like.
Well just to keep a sense of balance and a little stability, here's a place to voice your opinions on what bits of the game you already love and hope will never change (much)!
A couple of mine to start things off :
Attack while moving (Especially the melee) - Not just the mechanic, the animations for the most part feel just right, I just like it.
Knocking back still living small units by various means - I especially like the added damage when they land, lovely little touch.
