Now....why should summons be nerfed? They are helpful for casters fighting the scale of hard monsters in the game. Im a druid, my summons help me, but that is the point, my druid has significantly less ability to fight than a regular fighter and so forth.
If you want to solve this problem. Other than Gil and AE who think summons are just to powerful, which I don't agree with, most people are arguing a PvP scenario where the caster hides behind the summon to attack a player. That is the strategy since the core of NwN, nothing new about that. If you want to take out a caster, be smart about it, run past the summon, knock down kill the the mage.
Or, Run called shot to the foot, proceed to beat down mage.
Or, Get a dispel scroll from someone (Hey Team Work!) wham, summon goes away instantly.
I think maybe adding some antimagic stuff for fighters and other non caster classes should be available to counter this stuff. Make the scrolls prohibitivly expensive so that lvl 1's don't have mord's disjunct and so that maybe a few lvl 12-17 chars have the scrolls, making them valuable, and useful. And there is the solution to PvP caster summons by using dispell scrolls.
Remember, this isn't a NO MAGIC server. If you're upset with casters, don't lower the caster standards, bring up the tank standards. There is no rule that tanks shouldn't have some magic, (DM book says it

Gil....You're standards of magic would have sorcs at lvl 20 only casting lvl 3 spells....which isn't fun or worth it

Summons that cast color spray are lame in general mianly because it effects you too if you get hit by color spray and the second reason is teh dumb summon keeps using color spray rather than attack. Most monsters can handle color spray at lvl 10 so its not too good to use. I would suggest getting rid of color spray all together on summons just to make those summons more combat effective (they are summons they combat for you, or why would you be summoning them? To have tea? Don't think so
