I have been playing ever since 1.0(ugh) and also 2.0 onwards. I don't think I have ever felt like Warrior has ever felt quite right. 2.0 it was OK as a life steal tank, but I think SE may have missed the mark for what they wanted the tank to be ultimately. Warrior has always been a class trying to hang onto an idea of what it should have been.
I ultimately hung up my warrior and finished out 2.0 with PLD. Didn't touch warrior until near the end of 3.0 just to level it, and the same for 4.0. Others would argue warrior was "top dog" for tanking in 4.0, but I didn't see it when I played. Like it was trying to accomplish to much, and everyone was And each subsequent patch update I noticed warrior was no longer ANYTHING like it was prior slipping further and further from it's basic core fundamentals.
Focus become more and more on DPS, and less on a coherent rotation for tanking that you can get behind. It felt like warrior to me had to do some REALLY fancy things to pull incredible DPS, don't get me wrong amazing DPS! I felt that I would do that better playing a DPS rather then being a tank trying to be a DPS. Again...I would hang it up after every expansion released...
5.0 Warrior is striped down to literally the basics it almost started with, and I started to enjoy the class more. Became my 3rd 80 after PLD and ASTRO. But Nascent bugged me so I didn't continue playing it due to the gimmicky nature of Nascent. The rotation was much more coherent and simple, but warrior felt caged though, and the potential was nearly there.
5.3 The cage was opened and now Warrior feels so damn...perfect! THIS is what was missing in 2.0...this kit! There are those that feel warrior is basic and simple, but I say so what. When I'm tired of a breakneck rotation on PLD, and switch to warrior it's like a stroll in the park, relaxing. I have never had more fun with warrior then I have now. Nascent perfect, Storms Eye perfect, DPS is strong, sustainability on point. I have not been on my PLD at all since 5.3 released.
Warrior may be my new main tank and I have waited for 6 years. Incredible feeling. Paladin's felt this 5.0 launch because SE knocked paladin out of the park. Least changed job this expansion. Now Dark Knights need there time in the spot light.
