RIFT - 5 Man Team Question

[Slimez]

Question for those that have been above level 30.

Is there any viability to running like 5 Necros or 5 Elelementalist (because they have pets)?
Or maybe 5 of an offensive healer type?

Do you guys think they can do any instances post 30 or do they require an actual tank?

[Kicksome]

You might be able to do some bosses with pets, but you really need a tank. Even with a tank at 50, some of the instances were brutal.
