Hello my fellow Eleshamans!
I was playing around with ZAP the other day, and I found out that when I get the Halion Trinket crit ep will be 0.02 more then haste!
I'll hit ~1680 or so haste with the totem stacked. And that is just with the Halion trinket. So yeah I just wanted to throw that out, that you can get enough haste to make it less worth then crit
