I agree with the fact that prange, over the years, has lost its importance. There should be something that makes a prange truly indispensable compared to other dps besides the fact that they facilitate plans and makes mechs strats thanks to their guaranteed mobility.
Previously, pranges allowed you to regenerate TP and mana and had very strong mitigations.
Didn't you bring a prange? you don't finish your rotation due to lack of mana or TP, oops. Didn't you bring a prange? prepare to die.

Now it's a: if you don't bring the prange you make 1% less global rdps. Clearly it's almost an insult.
