Only a very small percentage of people really enjoy Arena. Its the same thing when a guild thats professional with tons of experience and access to tests/beta down all the content quickly...eveyrone GOES OMG OMG CONTENT IS EASY. Meanwhile you can check a progress site and still see like only 30% of total guilds finished and easy boss like Magmaw (when he was current obviously). I just do not think this game will be the "Hardcore" game people want. In reality though I mean what is most Hardcore skill intense game out there right now? Hardcore is dying breed for MMOS everyones take is on the social, everyone can do everything model or "Casual Friendly".
Want a real challenge play some Starcraft 2 or something. Arenas just ruin the game all it does is cause imbalance and QQ everywhere. Who says you need to have a game created arena anyway? Remember old games where people would use the community to just make up there own events. No saying you cant make your own arena style idea, hell I would be interested. Instead you choose to cry and whine. Besides this info of no arenas has been out for a WHILEEEE now. So only one to blame is yourself if you felt cheated or you wasted your money.
