Two years have passed. Deep down, you know the answer
The design of this game is a mess of inconsistencies, unbalances, things that should have been foundations for future things postponed indefinitely and relatively minor things prioritized and rushed out by lead designers that don't have the single clue of what they're doing.
This 2.3 stuff is obviously chopped, because originally the roles were 4 and well diversified, now we have the bare minimum just to push out this feature and add a little check to the list of things "to do", something went clearly wrong.
What happened to the roles that were lined out before? Too hard to implement? So instead we get the option of a turret gunner and/or an SLF pilot. Thats...pretty pathetic to be honest.
Take some notes Fdev, it would be really nice to cover that up during the stream. A simple acknowledgment would be nice.
