Class system. They should revamp it, allowing to chose any job at the start, it reeeeeaally sucks to play all the MSQ 1~50 (285 quests) just to be able to play the job I want (RDM/MCH/DRK/AST/SAM).
Also, 285 msq quests from 1 to 50, there's so much filler...
Also, the non voice acted msq cutscenes... It's very big turn down for any player. Sometimes we get voice acting, and sometimes not, why? This is not the most succefull MMO game? Even WoW and many F2P has voice acting, much more than FFXIV. I'm asking only for the MSQ, even the non cutscene texts. Side quest is ok to not have. My friends skip all the non voice acted cutscenes, and it annoys me SE not giving proper love to the story telling.
