The current argument is that no matter what, if you have the skill, it's just as effective no matter what class you are.

That's bullshit. DoW can't AoE heal, they don't have the resources to main heal, but it's still a nice thing to have on your bar but by all means leave it off if you don't want it. I don't require my tanks to have sacrifice II, but if they happen to have it on their bar that's fine. Some spells and abilities are class restrictive as it is. Speed surge, tranquility. Extend that to spells down the line, but leave what is alone for now.

For example, Protect III/Shell III can be conjurer locked.
Sacrifice III could be Thau locked.
Aren't rank 50 abilities also locked in? I think it would be utter crap if I couldn't use certain abilities, or have my stats where I like them, just so the few of you can feel like the unique snowflakes you think you are.

Honestly? No one really cares what you're using to deal damage. Not all abilities are appropriate for the situation anyway. The more we see done with battle regiments the less whiney you'll all be about this.

Don't fix what isn't broken, at the very least wait until more information on the battle system fixes that are coming out before asking for FFXI-2
