Look.My set up tab:
There's a difference between what you WANT and what you NEED.
You don't NEED 50 chairs. No one is going to rotate sitting on 50 chairs every day of their life. No one NEEDS 30 damage skins. No one is going to change their damage skin to something different every day of every month. No one NEEDS 5 EQUIPs for every part of their body when they can only hold one. It's just absurd.
I know you like to collect things. But why make the servers laggy by forcing Nexon to increase your inventory by 20x? Do you WANT opening your inventory to cause as much of a lag spike as opening your Quest list, or opening the Smithing tab? If you want to know what you've collected, keep track in a spreadsheet in your own computer. Throw away the things you don't need. Heck, maybe you could even GIVE some of your items to your friends, or even strangers ("WHAT? GIVE THINGS? WHAT DOES THAT MEAN?").
The fact is, no one needs more than 50 chairs, 30 damage skins, 100 equips, etc. Sure, an increase would be nice. But an increase causes more lag when you open your inventory. Is it really worth it?
Don't get me wrong. I like to collect stuff too. I'm all for 20-chair bags and increasing soul shards to 20 per instead of 10 per. But I throw things away when I get a full inventory. That's just part of the game. Keep what you need, throw what you don't.
