Is S6 really the "engineer update"?
Slight, mostly trivial buffs for Boris and his worthless turret and a change to a passive for Crawford that removes is arguably more useful Critical Repair and replaces it with a singular extra rocket for rocket launchers, making him the de-facto "use him for rockets" engineer?
This took how many months?
This is the update to make engineers more interesting and effective? Because the only real change that appears likely to come from this is that people will play Crawford when using rockets and that's about it. This seems incredibly underwhelming, but who knows, maybe these mostly tiny changes will have an unexpectedly huge impact.
Edit: Honestly recon characters received more changes than engineers did and in ways that more meaningfully change how they play. This should have been called the recon update instead, lol
