Because I did a full clear of two WSK levels I only had time for two clears of the wave and Baal. I was initially concerned with Lister and his pack, but those fears were groundless. Based on just the two clears I found no difference between the terrorized waves and the hundreds of normal waves I've run and the same with Baal.
Yes, it makes sense that since Baal was already a 99, that he would be the same. I was hoping that maybe they would have changed his cap.
Frenzytaurs are no different for me either. It does seem to take slightly longer to kill a monster, but frankly the only time I've found the terror zone the least bit difficult is when there are three boss packs combined.
Having said that you have to remember what a beast I'm playing. Now ARGH doesn't do huge damage per hit, but he is simply overpowering. Hits close to 90% of the time at 5fps, huge defense and 45% chance to block,
So, I may not be the best one to ask. However, I've just dusted off my M'avina strafer and while I haven't played her in years she has so far had no problems with the few TZ she has run.
Oh and ARGH just hit level 96.
