Just a fair warning. I know a lot of you look back at Vanilla Enhancement Shaman as this crazy spec that could one shot people.
I mained a shaman in vanilla + have later experience with it. I am here to break your illusion.
First of all, as you might know, Enhancement shaman is not desirable in raids. We are around 50-70% of the dps of the pure dps / warriors. If you are brought to a raid it is because they want your windfury totem.
In PvP, if you go Enhancement spec, you are going to be pretty weak for the most part. Stormstrike is an ability that is unpredictable and glichy, some times not giving WF proc when you should have gotten it.
Your best bet, even for PvP, is to go Resto. Then you have an instant heal / lightning nuke. It is way better, in my experience.
You have a billion totems you need to bind like frost resist totem. And these are all very important in PvP. If you refuse to put down resist totem vs a mage you are in big trouble. We are talking 5 full bars of buttons that should be keybound.
You will be easily kited.
You die in 1 stunlock from Rogues.
Warriors will go shield and defencive when you burst, then you have nothing and they can bring you down.
You need to be very good with timings on tremor totem to make sure warlocks don't chain-fear you.
I also want to point out that the spec was nerfed in almost all patches of Vanilla. If these Classic servers are on the 1.12.x patch then you are long nerfed to the ground.
Another point is that the burst is good in early gearing stages. Once people start to get Tier 2+ they have so much HP that you can't burst them down. You both having pre raid gear is a much bigger advantage to you than you both having Tier 2 is what I am saying. Your DPS do not scale good enough.
But hey, when you are standing there, autoattacking and shocking people in Battlegrounds, every so often you get a great windfury proc and they just melt. And that feels good. It's just rare that it happens.
I know you probably have seen some YouTube videos of people one shotting but remember that they cut out all the times they don't get a windfury proc or a bad proc, that is most of the time.
I just don't want people to get false hope.
