I think my biggest criticism is that Argus did not feel like a final boss in terms of tuning, for normal. The fight itself is pretty epic, but it doesn't have a ton of mechanics, what mechanics there are don't hurt a lot, and it just doesn't feel like a step-up from the previous bosses in most respects. Normal KJ was also easy but he could still wipe even geared groups if they were careless day 1, we wandered into the fight like headless chicken and lost one person beyond the automatic group wipe. Hopefully Heroic changes that.
