It might be just one of those random mind tricks, but are there any skills in Sal’s skill tree which negates some of the effect of the Bee Shield?
I got all the other toons through UVHM just using the bee shield (just one those personal challenges) but Sal just doesn’t seem to rock it when switching from Zerking to using the Bee playstyle. Don’t get me wrong a Harold plus Bee is still potent on Sal, but i think the other characters were simply better.
