I'm leveling a set of druids, well will be leveling soon.. working on a mixed set that is approaching 80th.

Pretty much, will do the heroic grind in 3.3 with them (probably won't be 80th before the patch), and then use badges to buy Furious. I seriously doubt they will get far enough in arena to buy pvp gear.

The team is for having fun in battlegrounds with. In that medium, they will be a blast. But I don't think they'd do that well in arena, which they'll do purely for the points. And then possibly join a 3's, purchasing boosting with 2 people who are high rated, to get me to xxxx to buy whatever, with saved up points.

I think they'll do ok in battlegrounds as a team.

Typhoon, with five casters, kind of makes one of them being stunned irrelevant. Most of your battles are 5v1 or whatever. I'm sure they'll get destroyed quite often too, for the reasons you mentioned. But they'll be fun to play (very fun so far), and that's the whole point.
