A really easy way to make Swipe work would have been to have it proc either if you take damage with Sheltron active or if an ally takes damage with Intervention/Cover active. PLDs are historically bodyguards to the Sultanate, so you would expect the knight with the big riot shield to prod you in the back with it every time that you try to bully their wards. 'Oi.'

I know that interrupts are supposed to be more important from a tank perspective this time around, but I still think that I'd prefer keeping Swipe over Bash. I wish that 'counterattacking' was more a part of the tanking aesthetic.
