Stamina issue with Engine Archetype

Hi guys, wondering if someone can help, I’ve noticed there may be a stamina bug with the Engine Archetype, despite mine being max level and with AP spent on Stamina, and having relentless+, it seems I can hardly keep up and 2/3 times per game I have to stop to regain, I haven’t noticed this at all with the Maestro and Creator builds. it’s seems they can run forever. but the one who’s meant to be the Cardio machine dies midway through defending a counter…

can anyone else confirm if they’ve noticed that the stamina drain on the Engine Archetype is like considerably worse than any other archetype?
