What's to say? It's going to be a F2P but with cash shop WoW-clone where you run around getting 10 quests per hub, killing 10~20 of the appropriate mob type then turning your quests in for gold, xp and items you'll vendor. After doing this for 30 to 70 levels you'll do the 2 raids they have, whine about how easy they are and how you're fully kitted out in raid gear in two weeks. You'll try PVP but it'll be fucking awful and a stupid grind for shit that isn't as good as the PvE gear out there except for an item for one slot. You'll do the requisite faction grind for a helmet and an item that allows you to enchant a piece of gear. This will be required for raiding and it will be soul crushing.
Grouping will involve finding a tank, someone to heal the tank and 2~4 dps classes. Combat will consist of hitting your "Opener that causes attack B to do more damage" followed by "Pure damage attack B" followed by "Closer that deals super damage only if you hit A and B first!" This will be done by left clicking or tab targeting the mob and then pushing 1-2-3 over and over again. You will have over 20 abilities on your hot bar all that do the same thing just with a different particle effect. Warriors will have an ability that causes them to quickly close the distance with their target. It will not be called charge because that would be copying WoW.
Raiding will involve a lot of sitting around clearing trash mobs and then learning how to not stand in fire all over again. It will have a raid cap of 20 people because raiding is srs business and must be perfectly tuned! You will hate other peoples girlfriends for being fucking terrible at the game but still allowed in the guild because their boyfriend is a pretty good wizard and you really needed a wizard plus she sounds cute on vent.
Tradeskills will involve clicking on shit on the ground then clicking on shit in your UI while standing at a forge. The only items worth making after the first week will be bags and potions.
The game will claim that it is 'new' and 'innovative' and use phrases like "dynamic content generation systems!" to describe their version of public quests which will be awful. They will copy RDF from WoW (without improving upon RDF's many shortcomings) 3 months after everyone has stopped giving a fuck about the game. There won't be an original thought or idea at all involved in the making of this game. There will be player housing but it will be pointless unless you start to pony up and buy some StationCash(tm) to outfit it.
There will be a forum guild that lasts about three weeks before some established guild recruits the 7 people still playing. In a few months the thread will be bumped by someone asking, "Anyone still play this?" followed by 3 people offering to help the guy who just started or recruiting him to their guild. After 6 months there will be an expansion where we all talk about the potential the game had but then bitch about the things that caused us not to play.
