A wise Warhammer Order say goes as "kill the pet". If every sc where we have WL starts with the remark "kill WL pet first", I dont see any reason why it can't be the same for order. + if you die to %150 more pet dmg instantly maybe it is time to check your paperlike setup.
And if you think AM doesn't have utility then I would say you havent played against a good one..
If the new SH dmg is a heartbreak for order. The solution is actually simple.. revert runaway tac and kaboom, give the 100ft range back and lower the dmg as you feel neccessary. Current SH is simply the fruit of a risk and gain relationship for which no SH player asked.
