If we ever see ERLBL on a Partisan or Huit, U/LBX/AC2s and 5s will go to the wayside.
IIRC the Dev-fluff is that the Partisan is the only vehicle at the moment with an ICE engine and so is limited to ballistics and missiles only (so no laser Partisan ever in MWLL).
I would love a dual LBX10 Partisan. But it would actually be OP as it'd be the best AA vehicle and could defend itself. The Huit version is already pretty nasty though it doesn't have the staying power of a Partisan to threaten mechs within 300m.
Personally haven't gotten the hang of the quad LBX5 parti yet. I can do some good damage and rank up with the quad UAC2 one a little more consistently. I've had some good turn outs with the LBX5 but its hit or miss (no pun intended).
Saddest thing is that with the new costings I never see the RAC Partisan used ever and the Prime is almost as rare (I've seen it a few times, mostly folks getting 4K at start for AA work). Seriously why buy a RAC Partisan ever, when there's an LB-10&LB-20X Oro at the same rank with the same effective range?
RAC2s could still use a little more love (ie. removal of the bullet spread would enable it to be effective beyond 500m), this would make it a harder choice between Oro or Partisan at 55K.
For sure the RAC Partisan is OP at 49k, but the Prime? IIRC the Owens C vs. Partisan Prime battles of old were evenly matched, fast and a lot of fun...but now the only Partisan choices at start are the anemic UAC2s, or UAC2s with Light Gauss (meh, why not a twin Light Gauss/Mgun Partisan at rank 2?) and the LB-X Partisan (I've never warmed to it, even in this much improved incarnation), so I'd love to see the Prime back at 49k...It was always my favourite starter vehicle and gave the Owens Cs something to be wary of.
