Simply said, it needed to be done. As always this is phase I of many passes to come. While I liked the idea of quirks helping to solidify a mech in its roll, i.e. a Cataphract as a ballistics platform, or an Awesome as a ppc platform.
Things got very out of hand fast when mechs like the Gatling gun SRM Huggin, where allowed to exist.
Ghost heat was introduced to stop weapons boating, Made no sense at all to have quirks that encouraged exactly what another systems tries to discourage.
Thanks Paul.
