Sometimes bad builds have good games. You have enough cooling to keep a very steady stream of damage going.
the build looks excellent. (good damage output, decent heat and enough ammo) What do find bad about it?
Lack of secondary weapons, no direct fire weapons, slow, relies on LRMs which can be countered by map or mode choice or teams with ecm or multiple ams. Can be done on lighter mechs...
I agree with all of that but slow. It's got the maximum engine for a Highlander IIC. Not much you can do about that. But if you're going to boat LRMs, this one will work.
I was thinking slow regarding typical group speed of 64 to 81 kph. Yes, this does quite out pace 48 kph of the more fail LRM assaults. I think the better trade off is going to LRM 70 and getting the speed into mid-60s with other mechs.
