If melee players get denied from getting high class items for that much time, big chunk of them will get bored from mage supremacy. If low class items drop +1 and their upgrade limit is +7 also (and wood staff and other +8 drops are disabled), it would be okay but still not fine. Mages get more than enough power with paper sets and a weapon that drops from worms. 1 month is too much to get one shotted by mages and have nothing to beat them. Good luck with +6-7 bardish-cleaver against mage groups.
