Please make more comps viable.
Some comps are almost never seen because it's too hard to get enough (Guardian, Demon, Dragon) while others are much too prevalent or overpowered (Elementalist, Assassin, Glacial).
Something needs to be done to improve the champion pool, because there are many times you lose a game either because you can't get a coherent team comp, and/or you can't upgrade any units even if no one else is buying them. It's a tad ridiculous.
