For me who played Ragnarok Online since early days, I really didn't like FFXIV. While your first class is going to get a good boost in the start with quest and such. Any other class you restart with will have somewhat of a problem. Got to level 20 before actually just turning it off.
The main problem with the game for me would be
1. The loot system
2. The stats system
3. The level base monster system
4. The skill system
5. The quest system
6. Combat system
All of them can be found in other games, not improved or anything. Just slight change to it or none at all.
1. Its the basic, new gear every 3-5th level system. Boy haven't we seen it before.
2. I don't know if the stats in the game actually do anything useful for you, those that you can put out but I didn't feel special about it. The game just locks you to a certain stat system for each class and give you 1 point every third level.
3. Monster that are 5 levels above will do more damage and take less damage from you because they are 5-10 levels above you.
4. No choice here on what skills you get at each level. They give it to you. No choice for me.
5. Same system as most MMOs and nothing new about it.
6. My fight is pretty much this in the game, 1,1,1,3,2,2,2,3,1,1,1,1,1 Just pushing number 1-3 on all the fights. The game refill your HP and mana between the fight pretty fast so you almost always are full HP. So dying is rare.
The game really just took away your ability to actually build a class and put you on a straight path on how they think you should play their game. That never ends well with MMO, Eve is a good example of that. While I don't play it, I read stories what people have done and that's some crazy stuff.
There is little difference between my Mage at level 20 compared to another mage at level 20. Seems all the new mmos are moving away from old school and try to make it so mainstream as possible.
I just want to have some control over what happens to my character when I play a game, Even if I fail at that its still my character. I learned something. Now I just follow the flow like all do and get some class able to do most of the stuff.
