A Few Questions As A Newbie

is there anyway to stash items so that every class can access?
is there anyway to reduce lag? I was fine earlier today, but now im lagging beyond belief and ive died 3 times because of it.
is there a best way to go along with the game? should i explore every area, or only stick to a certain path?
any other tips i should know?

Enjoy it however it'll be most fun for you

I'd suggest trying each of the classes, picking the one you like most
Besides that, forums are always here if you have questions (:
