Rite of Ruin on Galio?
Since I've been having a lot of problems with mana and damaging turrets on Galio, I was wondering why rite of ruin doesn't seem to be used by a lot of Galio players? Would the passive work with Galio's basic attacks on turrets? Does it seem efficient? And if I was to build it do I want to rush into it, or is that too expensive?
