Character Slot and Inventory question.

I had a few questions I wanted to ask:

1) Would free character slots be given in the foreseeable future other than when a new class comes out?

2) If I were to buy a character slot, would I get a free slot if a new class were to come out (like Aran and KoC)?

3) How difficult is it being a DK? If I get more slots, I'm thinking of making one for kicks.

4) When do the inventory slots of KoCs increase and which ones when they do? I'm currently using my DW (73) as a mule and I wanted to know.

Thanks

I had a few questions I wanted to ask:

1) Would free character slots be given in the foreseeable future other than when a new class comes out? Free character slots are given with Cygnus Knights, Aran and Evan. Dual Blade does NOT give you a slot.

2) If I were to buy a character slot, would I get a free slot if a new class were to come out (like Aran and KoC)? Yes.

3) How difficult is it being a DK? If I get more slots, I'm thinking of making one for kicks. Depends on how you like warriors I suppose.

4) When do the inventory slots of KoCs increase and which ones when they do? I'm currently using my DW (73) as a mule and I wanted to know. I don't think they expand.

Thanks

Answers in bold.

Thanks for the answers. I'll think about adding a character slot but if I do I'll probably get it for Dual Blade now. I might as well level up my DW then too.

Edit: I was wondering if anyone knows what each advance bring in terms of inventory expansion.

I believe warrior one adds the most, bringing in Pots and ETC expansion.
Though I may be wrong.

Warriors are the adventures who has the most inventory slots earliest. Arans have more than that, making them the prime mules.
