At this point your casts become 1 sec and the extra haste is useless. I would suggest switching some haste gems out if you can.
I rarely use IV in when BL is up, I find it more useful to use about right after BL because then it wont be affected by any lag issues that may be in play, also use hasteproc trinkets that works fairly good for arcane spec.

Besides, i was more into asking about Bentusi having 2150 SP and having 5-6k AB on 3rd stack and critting for 16-17k, not my own hasterating
