Ever notice how many of the creatures you fight seem much less formidable when you summon them? I've got two examples.

1) Winter wolves - when you fight them, they have area-effect Cone of Cold breath; think ten packs of Dentyne Ice a day. Yet when you summon them (6th lvl druid summons), they do single-target damage. I suppose that's ok if you've got tanks in the front line with them, but really...

2) Shadowed trolls - it must take a proportionally lesser amount of damage to blow them into chunks when they are shadowed. I've had quite a few trolls just disappear, and only recently had one fall down and do the Rope-a-Dope against my enemies. I'd like to see this happen more often, although the spell redeemed itself because I was fighting barrow wights.
