From everything I've seenand heard about ffxiv from 1.0 and everything current; its obvious that changing 1.0's class system to a plain job systen (which they are acting like they want to do) would have been too difficult at 2.0 since so much was already made. However classes, as applied in XIV, are against every other FF title in the series. In other FF titles they're called classes but are the JOBS. Yoshi-P has stated in live letters and interviews that many of the changes he's made is to put it back in line with other FF games by returning the FEEL of the series to XIV. The class system is one of the few remaining break-points that hasn't been changed over the course of 2.0 and with 3.0 looming and three Jobs being stated as Classless, I think the 3.0 patch will have a number of changes to the Class System we see today.

However, to everyone saying that with the class system gone, so to will be cross class skills. lol The system for that isn't restricted to classes. a WHM will still be able to set Swiftcast, a WAR flash, etc. But the abilities are going to be listed as a BLM skill, or a PLD skill....not THM or MRD.
