Been struggling to find a good build for this mech (I almost always keep away from XL engines). This build is great for me. Stay with the blob, they will appreciate the AMS. The enemy has a tendency to shoot things bigger than you.
A simple common build but also a nice build. If you don't use 2x AMS you can think of other variants which give you either laser duration or heat reduction.
Also, as usual, slap in an XL 280 since its the same weight as a 275. Squeeze a little extra juice outta your speed/turning/twist. You can also take a couple points of armor off the head, put full armor on the arms. and be careful with leg armor below 40 on the crabs. People love going for the legs lately I've noticed as they are bulky targets.
