Hmph, he should only cast it once (if fury is >= 95%), but I guess there is some problem with caching, so he thinks that he's still at 95%+ while casting sprint multiple times. From what I can tell, he casts it like 2 times for me, but very quickly, so it doesn't really matter. The next thing you can try is to play with TPS and Cache Refresh Rate (the Advanced tab). Decrease cache refresh time and/or increase TPS (watch CPU usage, because this can have a huge impact on performance).
If your barb has tornados generating fury with 90% crit, then maybe the bot doesn't register the fury decrease as it appears he's still at full fury. In that case, the cache tweaks could work, too.
Yea, it crashes when changing variables. Pitty. It also sometimes crashes while reloading item rules. I guess thread synchronization doesn't work all too well.
Also, Test Backpack Scores and Order Stash buttons generate exceptions (even in the old Trinity).
What can I tell you - many bugs to be fixed still, but fortunately, works for me.
