U can get more from the lasers really. Those are the core of the dmg of the build. Also the trouble with SRMs is the range, an increase seems wise.
The range is certainly one of the strengths of this build and the punchy pin-point damage application. I put in the Lplas range module and you can really reach out and touch stuff. Also this thing melts jenners and firestarters, it's not even funny. I did something remotely similar in the 2D2 and I didn't like it because of the fragile arms but the hardpoints on the 2K are vastly superior for this kind of shoot & scoot build So far I had 4 matches in it and none below 400 - 500 dmg and I didn't really try to do well. I'd go for XL280 though because it's the same weight and I omitted the AMS for more heat sinks, so my version is super simplistic but it's all about the lplas / 3x srm4 anyway, the rest is make-up
Glad u like it it Used the XL275 for standards, it comes stock with a lot of mechs, so many ppl have it, also is the top engine of most Centurions and 50 tonners
