i had a 60 holy/disc twink and i was pretty happy with him. since your gonna go 59 twink you should go ahead and get the 63 sp on the staff of twin worlds and get 10 stats on a goldweave tunic but thats only if you have bc and wotlk, and if you dont get them now. i have no clue why anyone would twink their main unless they just wana rp in it or lvl faster and get a healthy balance of pvp and pve in. really though just go ahead and be a scrub and "twink" a deathknight for 59 which is ok i gues but considering how many people actually have 59 twinks i would just flat out make a 49 or under.
