It's the multiple characters that take up time. Especially if you summon an army of critters and have then on multiple fronts and what not. Single characters aren't bad unless you just don't know your character or are very inattentive and need a recap everytime it's your turn. I had a drow spider druid who summoned lots of spiders, it can be tedious even if you're a fast play with your stuff together.
