BrioS made a good video about a build like this. His has 9 URML's. It's a cool enough idea to tempt me to take the EBJ-Prime(S) as the loot bag prize this Xmas instead of the Grasshopper, Zeus, or Warhawk. I have my Esprit de Corps set up with the many MPL meta, and am seriously contemplating claiming another Ebon Jag for playing with builds like this.
I was wondering what mech to build... this could be it! The low and wide arm mounts for AC's on the EBJ are terrible. You can sacrifice 1 ERuL to get the UAC's into a much more manageable peaking configuration: _
Yeah, I didn't leave mine like that for long, or with the ERUL's either. Now I run it with UAC10's on the ST's and 4ERSL's in the arms.
