I could see them being good with a party that laid down a lot of zones.As for ensnaring swordmage, my opinion is that ensnaring swordmages don't work well with anything--they should just be shielding swordmages and be done with it.
The answer to this is, IMHO: is anyone squishy?Think we'll suffer without a pure defender?
