MMORPG like Ragnarok Online

I love ragnarok online to death, but I just can't stand the lag, botting, and diminishing community. For those of you who do not know the game ill try to explain the aspects I am looking for in another game for some guiding help:

- I love the stat and skill allocation, where every level and every stat matters, and not only does everyones gear and class matter but also the way you spend your stats and skill points. Basically, I love the uniqueness each character can have (even if a few reacurring builds are the dominant ones)

-The endgame pvp, otherwise known as WoE, is amazing. Not only is the twice a week siege castle pvp rewarding, but the guilds that manage to "win" are glorified with their emblem all over the castle and get special access to leveling areas. The normal pvp is definitely lacking, as at any given time only a handful of people are participating so of course this can be improved.

-No instancing, all the boss mobs for endgame PvE are open to the public. If you want to be the best if you have to hunt the mob down and truly be the best. Much like outdoor raid bosses for WoW.

-A lot of itemization and unique upgrades to the weapons ands armor.

-Tier 2 classes; meaning that at a certain level your mage will be able to "evolve" into a wizard or sage. Basically, more then 8 classes that WoW is sporting at the moment.

For those who cannot refer to my ragnarok or world of warcraft references, I tried my best and hope you can give me a guiding hand to a great new game with a solid community.

Thank you
