And how on earth can Angels backfire?

Hehe, I'm to concise/cryptic/tired for my own good

My comment was more strongly pointed at Hydras (oops - dead poisoned army) and communions (exploding armies, over fatigued slaves dying in droves)
Angels can't backfire of course but used wrongly they will be counter productive. This is a general statement that's true for most summons. Some examples that do come to mind are using Seraphs against rival astral nation and sub par usage of harbringers (which can be awesome in some situations and pathetic in others).
