The large r-e laser is an interesting weapon with its 1:1 damage/heat ratio, and only slightly less accurate and heavier than the much-maligned IS large pulse, all with better range. I think it's a good main gun for a latter-era Guillotine Not sure how I feel about the rest of the weapons mix but I think it could work. I'm less sold on the medium re-engineered lasers. It depends on the prey it hunts, but a lot of the time a pair of medium x-pulses would be the strictly better choice, and that's what I'd roll with were I behind the stick. Gets you a ton back, too!

When it comes to the Rocket Launcher, I get trying to keep the general weapon profile of the Guillotine, but I'm not sold. It's my personal opinion that RLs are more of a deterrent (and a crit-sink

) when mounted on a 'mech than anything else, and a single pod doesn't get you much boom or much fear. More armor might serve your mechwarrior better.
I actually kinda like the LPPCs here. The capacitors give you something to do when visual contact is broken or the shots you have on offer suck. And a bit more reach doesn't hurt.
