I'm going to try one more time because I don't know how else to explain it. Let's look at drk vs. pld then. (I'm just going to go through what you listed, without even contesting them.)

Drk lost shadow wall, scourge, low blow, reprisal, dark dance, delirium. You want those 6 abilities back PLUS keeping the 4 abilities from pld and the one additional ability from role actions. 11 abilities.

Pld lost rampart, Convalescence, Provoke, Awareness. Pld gets to re-equip them with one additional. 5 abilities. (We don't get to re-equip what we lost from class...war/drk do.)

Even though all the tanks are comparable in dps. You want to hike up war and drk dps, def, and sustain. Then keep pld exactly the same and don't see that it would burry pld in terms of balance. I've already stated twice now, drk should get one extra def cd.
