Exactly this. Seems so dumb to me. The focus of the whole thing is to get the final boss down first. And they were second, but because of how the points are weighted on position and not relative to time difference between the kills they were placed 6th. Completely illogical.
make sense, somehow, but tbh, most of guilds that killed kephess so quick were ppl that avoided first 3 bosses with hm lockout, so i dont see a achievment on that, tanks are rly a hard fight to get thru without the right strategy
