4/5, Good build, especially for moving in force. The big 'mechs really like the ECM umbrella. It runs hot and you need to make sure you can manage it. This build works good for this chassis.
4/5, A bit hot for my taste, but still a classic good build. I vastly prefer the 5x ERML / MaxEngine build on the Grinner, though.
I think I may switch to 5xERML, since I'm already running the big engine and I'm having trouble cooling lol.
I've had good success dropping the arm MPL for an ERSL and switching the engine out for an XL280 to run a little cooler.
