Some Questions from a New(ish) Player

Hi,

I'm relatively new and I have a few questions about some of the mechanics of this game.

1. If I buy a feature from the shop like extra stash space, does that affect all of my characters or only the one I'm currently on? (Will they all get 50 inventory slots or do i need to buy it 3 times?)

2. Are any items ever bound to a character or are they all transferrable through the stash?

And a few questions about PvP:

3. Do you get anything for participating in PvP or is it just for the k/d stats?

4. Is there a way to do arena PvP or CTF in a queue instead of just joining games that are already going? If not, that's sort of absurd. Without an equal start, you can't really call PvP balanced by any means, and those stats are pretty much meaningless.

Answers to any of these questions would be greatly appreciated.

Thanks.

1. No, you have to buy multiple times.

2.all items al far are transferable through stash.

3. Just entertainment.

4. No, but moat people will do fair 1v1s if you ask.
