Guild Wars 2

Whilst i wait like many people for my account to be rolledback after a hacked account and clean out, is it worth logging in at all? i mean i will most certainly loose progress and any items earned right?

Will i miss out on my Wvw season progress as a result?
Can i level an alt and still keep progress?
Can i store any items ive earnt in a guild vault as i believe they cant be restored?

I am having the same issue preventing me from dowloading the client
