Hey. I wonder which way is better and faster to exp with boxed alts, Iam asking for interlude when the cap was still 20 lvl difference.
1st way: Keep your boxed toons in party since lvl 1 and exp them together.
2nd way: Exp your main solo untill he is 19 levels higher and then power level your alt.

I'm currently rolling powerlvl, but it gets worse when u need spoil on same lvl as main ;d

whatever u decide ... u will need decent buffs to plvl lower chars so u will need high lvl buffer

when i was lvling my aw back in the old days was like this ....

started with main then made wc box lvld solo with wc till 40 then in pty with aw till i got VR lvl 2 ...i think its around lvl 60...its np cause in cata u xp rly fast...after i kept wc out of pty till i made 78 then i made cov in Dark Omens cata in duo

Depends on classes too, big difference in lvls will make it impossible to recharge mana if you rolling se/ee as box
