Here my biggest problem: What do you actually want? I *stupidly* assumed you only wanted what you specified. 1 Class for 2 jobs. In some post here you go like "hey let's make classes till level 50"... that's not how combat classes work. I guess i should have had the power to read your mind. When do classes stop? Never? At max level basically? Then you just halved the available classes (formerly jobs) effectively. That will go over well... if not then where do you stop? And how do i level? Let's say Dragoon and Reaper need the same class. Once i hit 30 i can become Dragoon. Let's also say i level as a dragoon to 70 now. Can i become a reaper now? Or do i need to level the class again? Or did the class get exp with the job (like current combat classes)? If so this will make Dragoon to level 70 become a requirement for Reaper. Not any job. This is what i meant. It seems to me that it only limits access to certain jobs. Nothing else. Let's look at it another way. Dark Knight and Paladin share a class now. I got it to 30. I can unlock both. If i choose Dark Knight what was the reason to level the class? Keep in mind: I need to have a level 60 and be in Ishgard for Dark Knight anyhow. So why those levels? To get into the role? Maybe it's my first tank and that is actually fair. However i leveled a basic version of Paladin NOT Dark Knight. Now i have a greater chance to play badly (if i'm new). Third example: If White Mage and Scholar share a class... i level that pure healer and then become a scholar. Now i probably overheal and forget my fairy at first since Scholar plays different then Conjurer.
Most people argue EXACTLY the other way around. We now have more jobs that classes (just speaking about battle jobs & classes). So why the classes? Would you be OK with everything being a job? I mean what if they removed classes, let all jobs that had them start at lvl 1 (and maybe let every job start at lvl 1) and turn DoH and DoL to "Jobs" (maybe just in name) and call it a day?
