Walks-Like-Thunder is literally impossible to do with a small group unless everyone is DPS, a pickup group of 10+ people will take upwards of 30+ minutes to beat him. The totems that heal him take too long to break, and he becomes invulnerable way too fast. This was more managable at the release of Murkmire, when there were 30+ people at any group boss, but now there are around 10 at most, and it takes an eternity. Please, fix him, this fight is just unfun.
