as was said, mages cannot carry as much stuff as others, more items in inventory means people will be able to run with 3-4 different sets having all the debuff resistances depending on situation and they wont even suffer from overweight, because lel, lets increase weight limit
also point of using weight buff from EE means you need to manage buff slots better, you need to buy buff books so you can actually have it
hell if you dont have EE and you dont want to box it, you have even possibility on this patch to increase it with fish stew, it will just coz you 1 buff slot
