The greatest problem facing summoners in my experience is multiple casters using Dispel Magic. Even lower-level casters will get lucky; a caster of equal level has a 50% chance of succeeding, but two casters of 4 levels lower will also have about the same chance between them (70% chance that either will fail, 49% chance that both will fail).
In our group's last fight against a large mixed group, when we were heavily outnumbered, I thought summoning would help balance the odds. But two clerics dispelled the first summons and one more used silence to interrupting and ruin the casting of the second. So, just went ape on them instead. I guess next time the rule is "kill the clerics first" before summoning things to take out the tough fighter-types.
This brings up a different question. Say a Summoner has a ring of Counterspells and is standing in the area of effect of a Dispel Magic that contains both him and the summoned creatures. Will the ring counterspell the Dispel Magic even though the summoner isn't specifically targetted?
