>_> WoW is a good MMO, but a terrible game.
They really dumb things down and abuse the feeling of accomplishment that humans get when they are rewarded. Quest-centric gameplay which makes grinding look less like grinding, but its just a different color.
Combat is marginally engaging, and their balance issues seem to cause major shifts in gameplay so much you could theorize they're doing it on purpose.
Of course, this kind of description applies to 95% of all MMOs ever created, and thats the thing. Playing WoW feels like playing Aion which feels like playing Lineage II which feels like playing Ragnarok which feels like playing [insert this here]. You make your character, you apply stats, you choose your class/skills, you learn the ropes, you do your quests you level up, blahblahblah.
MMOs are strictly number games. You calculate and you apply. There is no REAL skill basis, its only Luck mixed with number crunching. Therefore, it really won't feel any different from another one once you work it down to bare bones.
Smash/fighting games also has applied calculations, but it requires skills and adaptation do actually apply them, if you can remember them. MMOs you can just open up all your numbers on a second screen, make a hot pocket, and stare blankly at the screen like a cow as your character makes shiny things happen on screen.
What Blade & Soul seems to offer, is the kind of real-time combat that would require skill in conjunction with the proper builds/strategies that would be a nice refresher for this bland and terrible abomination of a genre.
>_>;; And that's my rant.
tl;dr:
All current MMOs suck in the grand scheme of things, unless you have nothing better to do, in which case I'd say get better at smash and get some legitimate social interaction.
