1 druid tank, 1 druid heal and 3 rogue ? Viable for dungeon and wpvp ?

[Baltyre]

The focus is to have a fully stealth capable team for wpvp, seems kinda fun. (Maybe stealth run in dungeon ?)
But i know that the druid is far from the best tank, and i guess i will miss dispell magic from the healer (+slow cast from standard healing).
Do you think this is playable in dungeon ? For raid, i will probably focus on one character only.

And for wpvp, when you put aside the stealth part ?

Other problem that came in mind was : No rez on druid.
That can be really annoying. I guess i could stack the full team with engenering and jumper cable but it's not always working.

My memory from classic is bad (i was playing solo priest and only started boxing at BC) and i never played druids, so my knownledge about them is vague and incomplete.
