So many are either buggy, poorly thought out, or the combinations contradict each other in a way that just makes an already unrewarding activity, especially against hive, feel even more so. Sharpen. I can't tell you how often I've seen the protection not drop below 20%. Ignitions. When combined with Bound, it gets really annoying when they're placed in spots that push you away from where you need to be. As if the boss being able to OHK you wasn't already a significant problem by the time Ignitions would truly be a hindrance on top of the other hindrance. Ritual. Why design an augment that prevents you from damaging the boss while not in the circle, but the circle either has enemies, especially the suicide bombers, practically spawning with you in a death grip? And when that's not the problem, the fact several circles, whether it's bad location or AI intelligence, are placed in spots you can't damage the boss. Bulwark. More than a few times has the goblin not spawned or died from your team so quickly after spawning that you can't even find the Essentia. Just why? Bad enough players aren't rewarded much better if at all on platinum runs compared to bronze runs, but this is just unnecessary. We're almost in act 3 and rewards have not been addressed for COB or Nether, nor have these issues been addressed. Under normal circumstances, 10 minutes is plenty of time with a good team, I've had one where we consistently had 2-3 minutes left on expert, but these bugs and contradictions can easily screw up an entire round.
