Hey Fieari mate! 
I think the main problem could be to do with the physical absolute part of the Swarm Template. I think you could possibly allow martial types to deal 1 point of damage per attack on a fine swarm.
I agree, but it is one of those monsters that hovers on the verge of rulebreaking. It just is a terribly awkward opponent, one thats hard to kill, but will likewise take ages to kill 20th-level characters.
But then you can say, it is a mindless opponent and it doesn't have a ranged attack as such. Any 20th-level character can survive multiple rounds worth of attacks.

Fieari said:When I see a CR, I expect to be able to use the creature in a guardian-type role where the party has to be able to kill it. It's defenses are WAY too high, and while its damage dealing is low, it almost always can hit with it, so it deals consistant (if slow) damage while the party can do almost nothing to it. Melf's Acid Arrow maybe... but if the only access you have to that spell is Wish/Limited Wish, that gets expensive really fast...
