and about the "is mb overused enough to get a nerf" the only time i have seen it used in ha is when u only have / need 1 fire ele, otherwise u have 2 and they both take SH ( you can get more kick with SH then u can with MB)
baisicaly,
MB > SF/SH over time
SH / SF > MB for spike/pressure (modded sway)
so in pve MB > ALL !
