During today's SoO raid (20.05.2016) I noticed that the proc chance of Maelstrom Weapon ( http://www.db.pandawow.me?spell=51530/maelstrom-weapon ) has been greatly reduced.
I don't really have a prove since I don't have a video of how it was before but there are definitely way less procs than before (meaning ~2 days ago).
It appears to only proc from autoattacks and does not proc at all from windfury attacks or stormstrike/lavalash. As it says in the tooltip, every time you deal melee damage you have a chance to get the proc. This meant if you were very lucky, you could get 4-5 stacks from casting one http://www.db.pandawow.me?spell=17364/stormstrike (2 from the stromstrike attacks and 2-3 from a potential windfury proc).
However now, if you are very very lucky, you get 1 proc from casting Stormstrike because of an autoattack or so... This is just rediculous and makes the enhancement class unreliable and basically worthless in PvP (also deals way less dmg in PvE).
I'd rate it 8/10 important because it does represent a significant damage reduction, since a lot of dmg comes from instant-lightningbolts and ele-blasts that now have to be hardcasted or just omitted.
