it is NOT just AVs. in fact, with their resists, i am not even sure it will work on AVs and GMs. it is certain types of mobs, that have repel resistance
from Templarstone on first page
"So far tested at +4/8 Carnies can trawl mins/lts/bosses except the Steel Strongman Lts (they have resistance to repel )
Cimerorans well they would be on the list to not use it except as an opening. mins/lts/Bosses will all be pulled but once they are aggroed their version of Phalanx Fighting (gives them resistance to repel) turns on and then they cant be trawled ."
No one has mentioned testing it on AVs and/or GMs. My guess is that will be as useful as sticking a towel in the bulkhead on the Titanic. Might make you feel like you "did something"
Basically they took a completely useless power and turned it into a "It's Wonky, but it does things sometimes, YMMV" power.
Meanwhile, all the Devs that play will NOT take this power ever, and WILL take Fold Space.
