AcesHigh:Without using turrets, shield gen, or blessed immolation upgrade.  Is beaming the grunts and using a couple ehg the best way?  I want to put pressure on the arbiter, but most arbiters are doing this rush now so I have to be defensive.  What's the most cost efficient so I can retaliate right away?

I would make EHGs and some jackals. Let the leader and EHGs take care of arbiter and let jackals take down the SGs. Chances are arbiter can not use rage a whole lot if he is using SGs. He will either have to rely on rage or continue to make SGs.
