I'm waiting for criterion dungeons and the new pvp to judge, but so far, they are doing a great job at making a good MMO for casuals. Unfortunately for me, it's not enough. FF14 lacks in midcore group content, good healing content, long term content/grind that would last for the whole xpac ( might change with pvp ).
Should they change the dev team because I'm not happy with the direction of the game? Of course not.
Injecting new blood tho? Yes, please. We need more MMOs devs with a real interest in the holy trinity, combat content and long term goals.
