Clanners are awesome, but it'd be very disruptive to the current timeline of the game to allow Clan PCs, so I'm against them for now. As Warg said, maybe something for later on.<br/><br/>On Modifications:<br/>I'd like to use the Mechwarrior Online system as a vague guideline for modifications. For those who haven't played it, a basic mech chassis can be modified as long as the mods don't go over its critical slots or tonnage limit, but you can only swap weapons for weapons of the same 'class'. Ballistic mounts/slots can only be traded for other ballistics, missile launchers for missile launchers, energy weapons or energy weapons, etc. It allows for alterations without giving us all Omnimechs from the start (they should be rare and incredibly valuable salvage), and seems to fit the 'field modifications' I'm familiar with in the fluff (The hereditary<em>Yen-Lo-Wang</em>, for example, swapped its AC-10 for an AC-20 and finally a Gauss Rifle, and the field-mod of the King Crab traded its AC-20's for Gauss Rifles.
