Yeah. I love the fact that you can change classes with the click of a button no matter where you're at. I just feel that the current system is a wee bit loosey goosey when it comes to instilling a sense of a role to a certain class. People can argue this fact with me, but a lot of people agreed with me when Yoshida asked the second quesitonaire. I think it said about 22% of people think that one of the major concerns with the battle system is the class uniqueness. Next highest was spamming actions at 19%, and finally insufficient effect from attributes at 16%.
There are certainly a lot of things that need fixing in this game, but right now this is one of my things most concerned over. I'd love to see a sense of being unique like I did when leveling Samurai as my first in FFXI.
