1. The world is too small. This is my biggest issue with FFXIV. Having played GW2, TESO (beta), TERA, FFXI, and FFXIV 1.0 - I really miss the vast open world feel. FFXIV has too much content in too small of a space.
2. The economy. I can't afford anything and I can't make any money. I like how GW2 you can get the asking price for an item right away instead of having to wait for it to sell.
3. The game play. Everything is too linear and there is only one best build or one best way to play a job.
4. The community. Everyone is too focused on grinding and not socializing. Nothing feels friendly, just competitive or toxic.
5. Difficulty. The game is very VERY hand-holdy on everything. There is no sense of adventure or figuring things out for myself.
6. Battle. There is no sense of danger in the world and no use of technique. The things that are "difficult" are just a fast paced version of something easy. I feel like everything is based off of algorithms and calculation. There is no "human" element to my fights. No luck, no skill, no multiple ways to my goal. Just a best way to do things and death.
7. Level cap. I got to level 50 very quickly. I don't feel like my character really achieved much getting there as it wasn't much of a challenge. Aside from grinding to get slightly better gear, there isn't much joy playing this character any longer.
