Actual tip: You can pull aggro in the cannon, so make sure the tank has aggro or a hunter put a binding shot down so it cant attack you while you kill ads in the cannon. The grenades also pull aggro, so give it to the tank (or a rogue/hunter/priest that knows how to get off aggro). My friend also said that shrapnel can damage allies, but I've never seen this happen, be wary of standing in front of the cannon during shrapnel I guess.
I often tank this place, and it infuriate me that DPS cannot be bother with picking up the shells to shoot at the boss. I would if I could, but I'm busy tanking the adds.
This is.. literally how the fight is supposed to go.
Petko, honest question, but what's your intended audience with these articles? Point is that I feel like it's missing the mark regardless of it. Anyone seriously doing 15+ in premades will know all these tricks, and pugs just running Vault keys or doing leisure runs will likely not read these. The off chance some do, it's unlikely a pug is coordinated enough for one player with knowledge to sway the others into using these. It's especially relevant for this article: it's the intended way to do the fight, dungeon enthusiasts will know, others that don't will likely not read this.
