Well, I gave it a try. I went to Heroic UK.

The first corridor is hard and frustrating but managable, it all comes down to pulling carefully. I still lose a few pets quite often. When it comes to three or more mobs packs, my druid just cannot follow. The hunters spend their time rezing their pets, hence not doing dammage. So every pack either takes forever, or ends up in a wipe. Just *one* regular Heroic UK mob takes one of my apes down in just a couple of blows without heals. I guess it comes from the lack of defense stats. I can only imagine how fast a phase-two Ingvar would tear them down.

Conclusion : Heroics without a real tank is a no go.

I respecced my hunters to Mark, and will take them individually for Heroic UK trips with my PVE group until I get them all the nice crossbow.
