I picked this up over the long weekend and played a bit. Just wondering if those who are playing more might have any recommendations on which heroes I should consider buying first. Right now I am leaning toward Valla for my first purchase. I have been playing her lately and she seems to have a good variety of roles she can fill, as long as I don't get focused down by enemy heroes. As a plus she's not too expensive at 2000 gold. Or maybe there are others that I should pick up first?
