best of luck to you dude, I don't have much to add that hasn't already been said here
my advice (if you want it) when healing a squad is to always stay with the party leader no matter what. if someone goes running off and they aren't a wr then just leave them. also 80% of the time you should puri before you heal
also your "3 mag 1 vit 1 dex until I have 80 dex" bit took me way back to my first days of pwi... back in the day man...
