thats a good way to set it up.

your c account that is linked to more accounts, can get alot "granted levels"

which means u can take several classes, so once u get bored of one setup, u can just pick a new class thats lvl 60+ from your "c" account and replace it with the current class from the c account.

i really think its the best way to go since u can keep rotating your setup until u find the one that works best for u.
