Ontop of that S.E take the time to make sure that the changes they are implementing won't swing the problem in the opposite direction, as altera said Blizz did with DK's.
My main was a Gnome DK all the way through Wrath, when Cata came out I didn't want to play it anymore because it was too much of a 'win' button and lacked the fun of any real challenge, so I went Gnome Priest only to release that they'd been hit with the nerfhammer too and had absolutely no mana at all XD
So very happy when I came here and found a play style I enjoyed with enough of a mixture between difficulty and do-able without an inherent 'win' button like most other MMO's have with their cookie-cutter classes.
But to a little bit more topic...
I'm hoping S.E's next single-player FF game doesn't follow Final Fantasy 12. I was dissapointed quite a lot with that game as it felt more like Final Fantasy 9 with the final Fantasy 11 battle system. Airships, castles, a blonde thief main character.
I'd like S.E to make another pseudo futuristic RPG like their more popular FF's, FF6, FF7 and FF8. They all possess the classic swords and sorcery RPG traits but put into a more modernised or future-view perception. FF6 had robot suit thingies, FF7 had... pretty much everything, FF8 you got to go into space!
FF9 felt too much like S.E's take on the Legend Of Legaia plot.
FF10 did well and that had a sort of 'post futuristic catastrophe' thing going, where although the technology was no longer there, it HAD been there and you see it around the landscape.
And I'm one of the few people I know that actually liked FFX-2, I thought the class switching and battle system in that was quite enjoyable, and though it lacked a little in the graphical detail of FFX (which I thought was a tad strange) it was good fun to play, and the soundtrack for the most part had a fun bouncy happy feel to it.
However since I hadn't (and still haven't) completed FFX yet I didn't want to delve too far into it for fear of ruining the FFX finale, which I heard was something of a tear-jerker.
I haven't bought FFXIII yet but from what I've heard so many people say about it I don't know if I should. I always loved exploring the map in previous FF's and I've heard 13 doesn't give that option and that it's sort of like a constantly flowing plot with no real control over where you're going. As much as I like plot, I also like to wander around looking for tidbits and secrets, so if the lack of exploration is true for 13, I'll give it a miss, unless 13-2 turns out to be good, then I'll have to get 13 to see the story before I play 13-2.
