I think the game needs more activable items!
I think keystones should be transferred into bunch of New activatable items, they are too strong to be given freely imo. i think these items should cost a lot, but gives an active as strong as an ultimate. like: Mana depletion/regen active, Sacrifice yourself to heal your team/ damage enemy team..
i dont know something like that.. and i think more activatable items would add to the skill cap of the game, as to when and where to use them.
