You get what you give. If you actually want some help you should clarify. Do you have a budget? Do you just want us to post our BGs? etc. "LF IS META k thx" isn't going to make us want to help you.
Uh, but battlegroups are limited to 30 runes. You have 40 + Bastions, MoIF. Either you flunked 1st grade math or you are living in a fantasy world.
i would also like to know what an IS barbarian meta bg looks like. no budget. edit: if you could include replacement options for the more expensive runes that'd be good anyway.
Quit being a lazy ass and look for ten seconds in the IS forums. there are tons of threads just like these http://forums.poxnora.com/index.php?threads/barbarian-bg-discussion.6975/
