Well in my experience there are very few casters who do really well in EEs. I would take my paladin over most casters any day. The reason I even found out I can handle EE mobs on my own is because everyone was dying left and right despite usually having a caster when I was farming my 375 favor and I had to pull through time and time again.
Yes, having the mobs held, webbed or danced is better than having them tanked, and it's even better to just have them wailed. You are not going to have them CCed reliably though unless you are one of those people who are scared to run with people they don't know. I run with the first 5 who hit the LFM (as long as one is a healer) so I can't control what other people bring to the group, but I can control what I bring to the group, and what I bring is what usually gets the quest completed even if other people don't do their job properly. This is why I build my paladin the way I did, or why my wizard is necro-specced instead of enchantment.
