well my friend recently hit 61 on his account that i recruited and he didnt grant any of his levels till today( yes you can save them )
and anyways he spent 29 on my lvl 31 warlock and bam level 60 warlock who i am probably going to level to 70 now instead of letting him sit in my character list unused
most likley common sence but i thought id post it to anyone who doesnt have common sence
