Don't like Blue Mage? Here is how to convince SE to change it...

I think if SE allows BLU to enter duties, they need to make it so that the only way to keep any abilities they may learn inside the duty is to actually finish the duty, and not leave early. I don't know why, but I foresee that happening. "Welp, got what I was looking for, toodles!"

While I don't disagree with you, talks of punishing players more severely have been around for any number of reasons and nothing ever changed. There's a penalty in place for that sort of thing. Otherwise we're going to have to start a list, for instance, the infamous "healer hit 70 mid Castrum Abania and bailed as soon as they lost agro". Nope, can't keep your exp unless you finished the instance.

(Which is actually an interesting system, but is also horrendously punishing for people who had legitimate reasons to leave in the middle of the instance)
