I have waited years and years for mission exit at boss in SL missions.. then when 18.5 added Insurance Claim Recall Beacon to vet shop I spent 50 Vet points for it.... Unfortunately by this point I had done so many inf missions over the years that it felt like too little too late.
Instead of wasting time running out of inf missions , I felt like I was wasting time having to try to get or form a new team every one or two inf missions, Often to no avail.
But now 18.6.15 finally adds exits at boss...It's really too late for me now.. But hopefully when the gfx engine comes out I come back to the game and will appreciate this change.
