Saiichii just sort of threw a bunch of nonsense in there, it would seem. I don't mean to insult but you did, Saii. You sort of contradicted yourself all over the place.
+2000 weight making the game WAY UNBALANCED? How is that even the issue? You already have pets throwing the weight thing into an abyssmal pit of unbalance.
So what other proof do you need? I dont want to carry around a pet to carry loot for me when I could have a skill, yet I have the option to gain 15,000 weight capacity from a pet if I deem it fit, I would much prefer a simple gain of +2000, or anything from that down to 1. I think its fair for the classes that dont get strength to be able to collect loot aswell without an ass load of trips to Kafra.
Weight is limited in TOH already, so it won't break that either.
