Fear not, I did not misinterpret your position. If anything, I didn't mean it as if I were criticising you personally, if you thought that to be the case, I apologise.
As Kalise said, the implementation could have been way better.
People like Rei, Valde, and many others who offered their input, have come up with a solution that would please the vast majority >at this point< where all that would truly be necessary would actually be for SE to put in the effort.
The only reason one could take away for the current situation, let me be plain here, is most likely laziness on the part of SE. Although Kalise suggested "spite", well it's possible if Yoshida and a couple of other devs had their personal reservations.
To me it seems like BLU was just, and pardon my expression, spat out for the sake of cheap content (and cheap it was since it didn't last a second) so close are we to Shadowbringers and they bring BLU out to advertise it.
There are things that you simply can't do much about, achieving the perfect balance is impossible and both playerbase and companies need to stop going for an all-or-nothing on this regard.
In the same vein, if a business plans to keep adding classes (whatever the genre, MOBAs come to mind) these are going to have their impact and the more you add, the harder it is going to be to make everyone fit WITH their own identity.
Which is why I find it quite appalling that they decide to bring in the Gunbreaker as a FULL job, and then SE complains about the balance and class identity, when they're simply digging their own grave further by adding yet another job, following their own logic.
Nevertheless, BLU's treatment was 100% avoidable regardless. In this case, when things can be avoided, then going into them half-heartedly (limited job) can only hurt.
In essence, their excuses are a lot poorer than they appear.
