I'd suggest to change tiers not to be based on level (the actual 30/40/50/50party) but on ranks, maybe something as 1-10(sync to lv.20)/11-20 (sync to lv30)/21-30 (sync to lv.40)/31-40), so players are on about same rank, and sync helps players try to taste pvp early first, and second, they will gradually familiarize with their growing skillset.
