You took this way too literally. When I said 'for 48 hours', I meant that the window of time that the majority of players interact with BLU is within the first 48 hours of the patch coming out (eg the first two days). Actual interaction time with the job can be as low as 6 hours thanks to the discovery of 'BLU boosting' to massively speed up the levelling process. There's been some BLU patches where I've done everything I want to (that is, level to max, learn the new actions, and forget the job exists again) in less than 4 hours. And yes I gave the 'Limited Job' concept a fair go at convincing me, I've had the Morbol since like week 1 of it existing.
And considering the amount of time said content is 'engaged with', I find it difficult to say that BLU/Limited Jobs in general (because it'll likely be the same for BST) are worth the dev time, as compared to other longer-lasting content. And as I noted before, they're doing another Limited Job, and I don't have the confidence/blind faith that they'll be able to fit that into their cramped dev pipeline alongside BLU updates, without something else having to give way. Can't wait for BST to release, get levelled to max within a couple of hours, and abandoned to be 'weekly Allied Seals generator' status just like its predecessor. I feel bad for any BLU/BST fans who wanted to 'main' the jobs for raiding
BLU came out in 4.5, and I've yet to hear an argument as to why it can't be a real job, that doesn't immediately crumble upon the slightest scrutiny. Even Y-P's two most infamous 'reasons' fall apart when you think about it for more than one minute
Priority one: remove player friction caused by 'oops X player died so now it's a wipe'
Priority two: see priority one
The 'player friction' caused by 'the healer died and is now forced to watch the tank slowly whittle the boss down from 75% to 0%, completely unaided' is not as important to address to them, compared to 'player friction because wipe'. Maybe it's a simple numbers game? A wipe has all four players feel 'friction' by their logic, but when the tank can keep 2 DPS and themselves alive, leaving the healer in the dirt, then only the healer would 'feel the friction'
Why am I trying to find sense in SE's nonsensical design
