Hi there! For the few out there who, like me, just have been delivered their first Clan 'mech and have little experience with them, and C-bills to customize it, a quick and cheap field modification for the Prime to improve its survivability is the following: drop the PPCs and swap them with 2 cERLL, 416 points of armor (13 tons instead of 10) and 1 additional DHS. You'll have much better protection, a still respectable firepower with slightly better heat management and all the electronics you could ever want, all at the cost of 812.000 C-bills. It'll make grinding easier. If you feel like it, you could even drop the MGs and ammo to add 1 more DHS or 1 more ton of sSRM6 ammo.
Make the start "https" for it to post right. I don't know though...having just one SSRM6 seems a bit lackluster, especially for having to hold the target and being unable to torso twist. Might as well trade it for a regular SRM6 and be able to fire and forget with it.
Thanks for the advice, I finally got how to make the box appear. As for the config, it's just meant to be a quick and cheap mod to the prime variant, using only its omnipods and not the ones from -A or -B. I think it can be good for those who don't have lots of C-bills and don't wanna cannibalize their other 2 HBRs.
