Wpvp should't be enjoyable depending on class, otherwise I don't see the point of pvp servers. Although I had a fully pvp geared warrior most of the expansions, I have always preferred my lock. Legion put an end to wpvp for clothies and I dislike the wham bam, killed your clothie mam' play style.
Past expansion, on open world when a rouge got my clothie down to 15-20% hp, I would still have a chance to come back and I was motivated to fight, while now I only hope I will get to a closer gy.
