Thing is, I havent seen a great MMO release since WoW/FFXI...period. Some were for sure, better than others, but none seemed to last long aside hardcore fans of what have you. This is especially true for releases. FFXIV flopped harder then SWTOR did, by loads more. Non insanely challenging/long term leveling MMOs simply get snagged eventually because they zoom through and hit all the content within a few months...then get bored.
SWTOR was and is an amazing game. The voice acting, cutscenes, leveling and combat were all better then any MMO I've played thus far. Its main issue, and someone nailed it on the head, was its lack of challenging endgame content. The flashpoints were fun, but very limited after a while. SoA was the hardest thing to beat, but even then became fairly easy. I'd say SoA is as hard as AV but AV is shorter.
This and the fact FFXI/FFXIV ruined the idea of one class a character for me. I had no motivation to make more characters after my Jug hit 50. Leveling on the other side was alright, but I was still basically doing the same leveling quests over and over from before. With FFXI/FFXIV ... and I believe this to be its single best thing, I could switch classes with my one character. This by far is the best function I've ever seen, and games without it seem meh and not worth it to me.
