The ugliest situation come from where there are 2+ groups of 3+ beserkers, mainly because they set each other off and it dominoes very hard very quickly.
The incentive is not wiping.
I murder them simply because they’re heretics or skaven scum.
Once you get an experienced group, they’re not that much trouble depending on builds. The incentive at that point is to see all of the Elite kill spam.
If i have a bomb in my hand you can be sure it’s going to fly directly at them…
9 out of 10 groups I run with do not avoid them. Even pub groups. Most people just take them out before the horde comes.
