NCU imbalance is a tl2 thing, sure not all proffs can get on ql 160 infused tl3 but they sure can get ql 200 NCUs from lvl 75ish.
Also, with the changes comming up, agents are not gonna perk snare high evade twinks, and when they do so they will do it for less. And even then they will still have to wait for AS.
Agents is the greatest imbalance at tl3 pvp atm, it is being fixed.
Enfs might get more powerful tl3 now but i think the real winners in this range will be evaders. Mostly traders, crats, mps and initally GA fixers until everyone have one of the other 3.
