Part of the problem with nature summons is that many of them work only against living enemies. Spirits of the woods and their awe. Lots of venomous creatures can't harm undead, constructs, and (if I remember correctly) many demons. Nature summons are good mostly against other nature summons (or at least living creatures).

I've just cast Creeping Doom. Pathetic ! 2 gems to stall 30 barbarians. They didn't even manage to deal 1 (1!) damage to barbarians. They are supposed to have weak poison. Creeping Doom looks like a very situational spell. It might be better than Swarm against certain enemies, but it's hard to come up with an example. It's much higher in the research tree and requires NNN to cast.
