I really am enjoying the class, but this is my first tank. So... with that in mind, I was wondering what I can start doing now to set myself up for when I get to 70?

What sort of skill usage should I get used to early so it's second nature to me later?

DA I know needs to be used when possible. Don't use the arrgo combo if not needed. Keep Darkside on always...

I know I am missing a lot so any linked guides or just your experience will be appreciated.

Thanks. =)
