What the shit are you even talking about? You didn't provide any type of source and your information was outright incorrect in addition to having a nice ol' bitching tone about it.
The person who suggested the Maelstrom Weapon change knew nothing about WoLK PvE mechanics and suggested a 12 second cooldown. Yes, that's right. A 12 second cooldown. He was obviously thinking about PvP and didn't think about the incredible nerf this would be to our DPS. I posted on that thread for him to delete/edit it immediately before Blizzard saw it and thought it was something we wanted. Obviously, he didn't listen.
Our DPS is about to go majorly down the tubes. The new version has to have a long cooldown or it makes it broken for PvP purposes. The whole reason Maelstrom could do that much DPS was that it wasn't that hot in PvP due to needing 5 crits in fifteen seconds. The new one is great for PvP but outright horrific in PvE. If it is implemented, we're in for some serious heartache.
The entire enhance tree will need to be buffed somehow. We're talking hundreds of DPS here when we were the low man on the DPS scale to start with. All the things that came together to produce our DPS fall apart with this change.
Lava Lash was cool for the old Maelstrom but is terrible for the new one. We'll be using Windfury instead of Flametongue so using it means we drastically cut our main-hand windfury percentage. Our mechanics will essentially punish us for using the new move unless Windfury is changed drastically. It is wrong that a Lava Lash could cost us DPS if it procs windfury.
This also means that fast isn't rewarding enough anymore so Static Shock becomes unwanted. It won't deal enough damage to warrant losing the mana regen of water shield.
Elemental Devastation downtime goes down a lot. It doesn't last as long as MW's new cooldown.
All this because some guy who liked PvP wrote a big post about talents he liked/disliked. What a disaster.
We had all better pray that Blizzard actually keeps it's promise to adjust our DPS to match everyone else's after we come out with our new gimped numbers. If they use the DPS from the old model, we'll be in serious trouble.
