Return of Reckoning

Hi, i have 1 question:
Can i do older missions to take, for example, scout medallion?

you have 1 tactic that you can res more fast, but first res you are knocked

i have archmage lvl34 and i build healer whit dps, whit res whit fast restore, and path of isha, ido high dmg per sec whit all curses, can heal fast and resurrect 3 or 4 people in 10 sec, only the problem is i cant heal alone
