I agree with you there, "Elynosgirl" =). Why do they even give you those lame level 1 potions anyway? its not like you can't go without having them even if you just made a new fresh character. Thats what Sit is good for, fight as much as you can before dying (and not remaining in combat) and Sit to regenerate your life. Most times potions are not even needed. Dungeons however is where I used them....if needed.
The "Jack of Clubs" I understand getting since you don't get them all the time from monster drops, rewards are random when you combine 4 of them, but thats ok I suppose.
"The loot box's cooldown should be at least shortened with 2-3 hours or 4 >.> at the current rates i will never get something good
And there are items which are not even implemented a use for them yet (erm... at least increase the base slots for inventory and warehouse....)" those would be nice to have as "Elynosgirl" said xD
