Removing FF is the only upgrade you need here besides some new lasers. Heavily inspired by @Sierra on Discord, I decided to make a workable KGC build fully focused on budget, using hammerclaws. The cooling is kinda overdone, so use it to your advantage if you need to spend some ghost heat on dual-fired AC20 power. It also allows you to use the ERML at range more, before the enemy gets in range of your claws.
