I usually have no problem with Tier III Blind Wells. However, this week, I have tried 4 or 5 times, and have not been able to successfully complete any of them. The enemy is brutal and seems off. I have been in the Well with rank 10 and 11 players and none of us can stay alive. Nor complete it before the timer runs out. This is highly unusual. I think the delta or scaler or whatever makes the enemy harder has been turned up to like contest mode or something.
