By the way the demon now has Arcane Doom which is much better the minion was nerfed because it needed to be very badly.
Yes the vigiliant minion was way way too powerful... and nuking the entire battlefield is "LATE GAME". The Stone Golem is also too powerful since his spell can strike anywhere on the battlefield. A group of 5 elementals should not be getting killed by a group of 5 lower class summons which have strike anywhere battlefield spells.
The stone giant only hits targets in a 3x3 square....I don't think it's too powerful (well maybe reduce damage a little) but I do think the elementals need more power they are afterall pretty high level summons and their power should reflect that.
Also if a summon has mana it really should be able to cast something. The Ice Giant has clarity as well but nothing to spend mana on. The imp and the minion should both have something around the level of flamedart.
