all this talk about solo worlds.... yes, on avg, you will not be going into long rounds... most of the talk prior to this was for worlds with very large alliance armies. There is no avoiding long battles with many rounds.
Also, huo, damage has been boosted since OC.
Range - 12 dmg per round
Damage - 21 dmg per round
Round 1
Range does 12, dmg does 0
Round 2
Range does 24, dmg does 21
Round 3
Range does 36, dmg does 42
The example you used is of a very very poor build. The example below is NOT meant to be about a dmg build, but to show that BIG battles will last much longer. This is an old BR i have and by no means am I saying that it had a good build on it! Simply meant to show that rounds can go very long...
