First of all thanks for your comments.

I decided to set my main focus on pve and so will add the shaman to the group while still playing a hunter as my main. For healing I will use the num block(top 4 rows, 3 columns..so I can define 3 actions per hunter. For example "1" heals the hunter, "2" starts chainheal on his pet and "3" is rezz..or something like that).

The totem support, heroism and the fact that I replace 3 tenacity pets with ferocity ones should not drop my dps in pve. One gorilla with earth shield, hunter hot support, and a shaman behind him spamming 4k NON crit LESSER healing waves(lesser healing wave glyph + Blood of the Rhino) should be a good tank, i just hope the shaman doesnīt pull to much healing aggro. And for big groups I just let the other pets offtank and spam chain heal.

Well for pvp the mobility sucks, but the group should still be viable and if not I just quad box with 4 hunters.
