Is it worth better to stay on the small guy? Or rather do one more round on the tall guy? Once the WA change color, stay on the small guy!
default color: white - dps the tall guy (top number higher)
red numbers: stay on the small guy (bottom number higher)
yellow numbers: probably worth to stay on the small guy (top number higher a bit)
The red color trigger counts with small guy having less HP than tall guy*0,8 - as tall guy stunning on 20% HP - so once is red, go for small guy.
The yellow color trigger comes with multiplier 1,2 instead of 0,8. If during the combat you usually getting the Death Shroud debuff, this number should be lower. If you are good with damage, it can be higher.
