What classes need the most PvP help, TWW changes?

What do you think are the most underperforming classes in PvP and why? And do you think it will change in TWW?

Ele and Enh shammy are two that really stick out to me. Ele is decent, enhance is as well, but requires a lot of ring almost and they both seem squishy.

Enhance more then anything.

Cloth and leather wearers are more tanky then mail users. But enhance is stuck in melee range the whole time doesnt have a turtle like hunter and is prettt useless at range unlike surivial which can have a short range window went needed.

We also have a heal that directly takes away from our dps as we have to spend maelstorm to use it.

The way it currently plays u need rng to quickly get maelstorm to spend on healing and trying to maintain dps in order to come out on top. If ur rng is behind u spend all the maelstorms on heals and ur dps drops too low to make a difference.

Enhance needs to play more like a bruiser and less like a caster with no range.

Holy paladin. Can’t contribute any DPS during downtime because you’ll run out of mana. Easily trained. Hardly any dispel protection (trash buffs) for its utility/defensive. Still goes out of mana the quickest because Blizzard keeps nerfing their mana regen.
