Isn't blue mage boring already? Or maybe you just find fun to run old irrelevant duties

What makes a duty relevant? The answer to that is different for everyone.

A mount? There is a morbol mount for clearing old raids with BLU, just like there is a mount from the latest savage raids.
An achievement? There is an achievement for clearing old raids with BLU, just like there is for clearing the latest savage raids.
Gear? BiS? You could unsync the duties to get a BiS for BLU, so that might not be motivation enough.

Personally, the morbol mount made them relevant for me and it does for many others but I've met a lot of people interested in the achievements as well.

And I fail to see how blue mage would be more fun to use in any savage or extreme because IT HAS A BORING ROTATION

Blue Mage has lots of abilities to rotate through. If you think Blue Mage's rotation is boring, then you will probably be bored with most of this game's rotations for the foreseeable future.

Also, if Bluemage became a "Normal" job with fixed 'Normal' skills, what would make it any more interesting then it already is?

The fact we could play it in all content without limitation while enjoying the aesthetic of a job using spells that mimic monster abilities.

They weren't even that far off with the original 49 spells since their power level wasn't as broken for most of them (exceptions were Ram's Voice with Deep Freeze).

Anyhow, a possible solution would be to simply introduce a 2nd BLU soul crystal. One for the current iteration, one for the balanced caster DPS many wanted initially and were malding about when it got announced as limited in Patch 4.5.

Putting aside my beef with the job design, I am actually jealous of the job.

To make the job have "content" they introduced arena-style solo challenges a.k.a. Masked Carnival (love it btw), a content log to encourage doing different types of content with a checklist and to top it off: an encouragement to do the old Extreme and Savage fights synced to the original level.

While I can "barely" fill the void of #1 with running Palace of the Dead or Heaven-on-High solo, the last one stings. I'd love encouragement to do old but difficult duties like Bahamut, Brute Justice and so on at their relevant job level, but there is no incentive (like a series of achievements like BLU has) to do so, most just blaze through with Epic Echo for poetics or to speedfarm some glamour and then never return. Once in a blue moon you find some gigachads doing that content, but they don't last long.

Asmongold's arrival has at least encouraged people to do various Coil raids, but it kinda stopped there which is a massive shame.
