How exactly are people being punished ?
i have 3 characters one my main who recently got legacy and my 2 alts i rolled to play with friends. one of the alts i was already advanced class when i unlocked legacy and the other i rolled after i unlocked legacy. i haven't missed out on anything, just because i didn't get that whole amazing amount of xp from 1-10, yeah i'm probably behind people who may have concentrated on one character and be a much higher legacy then me but at the end of the day it is just a bar moving across my screen it isn't giving me anything so why should i feel dissappointed cause i didn't get it before i leveled other characters.
After level 10 if you click your talent tree you can see the legacy page and it says all rewards and what not will be given when its implemented.
looking forward to any info on what the rewards are gonna be when its released in the meantime just playing the game same as always watching the bar above that more.
