well im telling you this
ive renamed banish to Guess which form to use this round
lately me and the other top 2 hitters in my realm
have been a bot all over the place in damage.

One day 2 of us could do our normal while the 3rd does 20% more then usual or the 3rd does 20% less the usual
or 2 of us could do 20% less the usual and the 3rd does normal.

The issue is 2 fold.
1. damage is in ranges so regardless of how many times you stun - you can hit the low range of damage on many hits in the round and not crit as often
2. stun rates - they are so random its not even worth figuring it out any more.
I can avg 14-22m a round
the best player can avg 18-28m a round
the 3rd avgs 10-16m a round

So as you can see it goes all over the place.
Then if you have only 15 rounds one day you may not ever have your REALLY GOOD rounds and if you went 4 more rounds you could have done another 100m damage.

It is definitely pretty random now a days.

Im not saying anything was changed
but if it was changed it wasnt today it was around the introduction of the casino
