I run the 1xERPPC and 2xMlas on the 5D spider and love it so decided to give it a shot on Ember. Lowered some armor and lowered the engine to add the 4 MGs for critting cored parts. I run atleast 1 JJ for getting over obstacles and quick turning when being chased.
I am using the build, except with 2 smlpls and a lower engine for more JJ's and MG ammo. I seem to be doing well in it, at least 400 damage a match. Very good for all ranges, not too hot, has the 4xMG's for spamming.
I'm rockin this build with an xl280 2mgs and 3mlas, consistently getting 2 or 3 kills and averaging around 400 damage.
