Currently the mechanicus power sword does not feel great on controller because it requires spamming R3 on right stick to do multiple chained special attacks. This can feel pretty awkward when the right stick is also what we use to aim. I don’t know about others but I find it pretty difficult to click the stick fast while also trying to maneuver and aim to hit multiple enemies.
Changing the mech power sword to function more like the arc maul, where one button press activates it to make regular attacks empowered, would just improve the weapon handling and feel a lot I think.
I think also many would appreciate a second mark for the weapon that had more vanguard light attacks. Or making the special activation a mode that changed the moveset a bit.
To add to the point on the awkwardness of attacks mapped to the right stick, full controller remapping options would be greatly appreciated and improved accessibility for a lot of players in general.
