The only difference is, BLU players are generally more vocal on these forums since very long time ago, so they receive more sympathy while COR receive none being a bandwagon job LOL.
I know you love COR, but... wow, no. It's not about going line by line to compare sets. COR has big time advantages that BLU does not, and that's pretty obvious. If they aren't going to address via job adjustments or specific mechanics, a job like BLU that is supposed to deal damage really should get some big boosts from JSE gear stats.
COR can do it all
- Buffs
- Incredibly powerful magical WS (particularly Leaden in the darkness-heavy current endgame content), to the point of being semi-broken good for much of the last few years
- Great melee, especially with Naegling. And come on, it's ridiculous that COR has significantly better Savage Blade gear than the A+ Sword Skill DD job that is supposed to be a master of the weapon type.
- Great ranged damage
BLU was bandwagon YEARS ago, and now still keeps getting shafted on gear when it's far past time for it to get a bit of a boost to catch back up. Just a handful of examples from the Rhapsodies-Present era:
1) BLU got stuck on a Su3 set with... a fast cast piece and a cure potency piece. COR got a set that is still staple Triple Shot gear.
2) For Odyssey (aside from all jobs Nyame), BLU got Gleti's, which is basically only used as (1) gear for a secondary WS (CdC), and (2) idle regain gear. COR got some very solid ranged/WS gear in Ikenga (especially the enm- on a job that sometimes really needs it)
3) BLU got one good Relic +3 piece (WSD/nuke legs), COR got incredible pieces for feet, body, hands.
4) BLU got a nearly useless Su5 weapon, COR got an Su5 so good that all three paths are worthy choices.
5) BLU got a rather unimpressive Aeonic, COR got one that's very good.
It's not about "LOL both got on Malignance and Nyame and some of COR's good gear is old." Lots of jobs are still using gear from several years ago. COR has ALL of the advantages though, and it's a little sad to see BLUs who have been starving for impressive DD gear on its JSE/non-all jobs sets wait for literal years for the release of this set and get uninspiring gear stats.
