1) Try getting behind the new rocket gremlins when hitting them. If you are in a party, get your friends to carry the shield and gun when they drop it. I feel like a big bully taunting them and holding their weapons above. I kinda like the mob for that; it's kinda silly.
Would be SO EPIC if we could fire off their rockets though when carrying them.
2) I thought the boss was pretty cool, but I wish it didn't use battlepods. I just think the challenge is artificial with battlepods because you have to wait for it to drop its shield, whack it a few times, lather, rinse, repeat. It feels a little chore-like to have to fight battlepods. Other than that, when I was getting to the boss it was so awesomely ambient, and the boss itself, and the facility exploding at the end.. I was like OSHI- five times through playing this thing. The content is so cool.
the expansion for me is not a lot of fun ... main two reasons
1.
the rocket gremlins cant be hit from the front or sides because their shields make them invincible
so unless you can hit them from behind they dont die which is beyond annoying ...
2.
end of expansion boss is just crap ... atleast you can hit JK / snarby / twins / vana upfront
you will see what i mean when you get their but for me its just not fun ...
