I said it somewhere else but this is just 2 incompatible mindsets clashing with each other. Yours is probably the more correct one when it comes to the current battle model, but ours stems from the fact that we do not like the current battle model and rphys was a way to continue playing pve without caring about uptime bullshit because what we used to enjoy in the game wasn't about DDR and uptime bullshit. Sure, that thing isn't here anymore, but at least we still don't have to deal with half the new model.
If it takes damage out of rphys and leaves it in the dumpster like it is right now, selfishly, all I can say is that I still prefer this because I can continue ignoring half of the current pve bullshit the game has been about since SB/SHB. But your vision or Lyth's is probably the best within the current system.
And to be frank, even when it comes to casters and melees, the mobility of other roles has been sanded down enough to accommodate for that endlessly increasing uptime/DRR crap so all roles are slowly but surely starting to merge together anyway.
