If you think the job system and the battle system as a whole hasn't changed since ARR, then you're probably a lot more tolerant and less sensitive to changes than I am. We've not been playing the same game at all for a while now. It's almost as if we had moved halfway to another game genre beyond the MMO part and that's my main gripe. Things changing and evolving to shake things up is to be expected, but changing the fundamental core of the genre is the best way to alienate veterans, and generate chasms in the community between the old guard and the new audience.
