Old system. You have nothing over level 20.
New system your sups are one level lower casting your healing is less.
The one level lower you won’t even notice. The 30% drop to healing doesn’t really matter most of the time, in pk you generally don’t want to heal in combat, in PvP it adds a little more resting. As a Low int race it might be a drain, anything human or better its minimal impact.
Virtues/shaman paths you need empowerment anyway.
So still aim for empowerment but you aren’t totally neutered by ranking past 20 while you get it. And getting it is as easy as logging in at the same time as your imm. Imms are really easy on empowerment compared to the old days. I suck ass at RP and have even pulled off 2 path scarab follower so you won’t break a sweat.
Druid is easily the most affected by having the -5 herbs but you don’t need herbs and by the time you can pull 3 you can enhance at least one aspect reliably. The FAQ on wiki solves the biggest time sink of learning where to get what herbs.
No transmute means find dragon and leather hp gear. No fly on healer just means buying some fly potions, 2 round lag on wrath just means you get less kills with wrath (mostly impacts shield ded)
An unempowered healer backboned some crazy hell trips in the last year just to throw that out there.
