Strength of the Pack
This should be an all-round solid elite skill. I think most people still use it, but only because the others are even worse in most situations. It's a skill that is mostly used for the stability, which counters CC, so it makes little sense to give it a long cast time so it can be countered by the CC it's supposed to be countering. The might sharing isn't even that great, just remove it and add a flat amount.
I'm not sure what you should do with this mess, but it's a waste of traits. You can dedicate 4 traits to Opening Strike and it would still be terrible without help.
I don't know why its cooldown is 30 seconds.
