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

It can change things. "Must have all spells 1-40" requirement to queue up for things in that level range means that people couldn't complain about you not having a spell.

As far as we know, BLU won't have levels tied to their spells. And even then, if a lvl50 monster teach you a powerful spell that you could set at any level (Like how role actions work, for example), people will complain that you don't have it.

By the way, a highly requested job being added as a job gets people playing.

Considering 1) it never happened during a dry period and 2) no new job started at level one since Ninja, you can't really judge if it would have been more useful to keep people interested. I'll speak for myself but I'm more interested in a lvl1 job with its unique leveling method and specific content than simply another lvl50 job to run content I already run with in any role with another lvl70 job.

Yes, keep some players playing till the next patch/expac while pissing off people that they turned the job they wanted to main into a "limited job" tied to filler content.

People are pissed by their own assumptions of how BLU will end in the future even before it's released, while still complaining that every content is always the same and nothing new comes in the game. And they'd probably be pissed if BLU was shoehorned into simply another caster DPS with nothing to really make it stand of. At some point, if you can't please everyone, you just make what you think is innovative and fun.
