Every guide I seem to find is horribly out of date in so many ways. I understand the concept of killing things equal to or a few levels above you for the slowest xp in the world... What are the other ways to get some xp?

I do my leve's on cooldown. I tried that battle thing, but it has a long cooldown and the xp reward doesnt seem all that great.

I heard there are also grand company leve's to do, are they on the same limitations as the regular leve's?

I'd most likely be going at it solo, especially at the low levels (10-35). I do see shouts for 35+ somewhat often enough, but I have not seen one shout for a party under 35.

So... any tips? :O
