One relatively minor change I'd like to see for the AtB campaigns in MekHQ would be to make it possible to reduce the experience point gains of administrators to something below 1 point per week, without making it zero.
The campaign really needs the option to alter the "Points per week" to something above zero but LESS than one. It currently allows only 0, 1, or values HIGHER than one. This can probably be done relatively easily by altering the "X points per week" to "X points per Y weeks", with "Y" being selectable, or by allowing "X points per YYYYY", with "YYYYY" being either "week" or "month". The administrators need some way of acquiring SOME experience beyond the generic "X points per Y months on a roll of Z or higher", which affects ALL of your troops, yet without getting 5-10 times as much experience as everyone else.
My current campaign: first contract for 9 months of Pirate Hunting. I show up a couple of days before the end of the month, and on the first of the new month, the pirates drop down to Low morale before I've even had a chance for a battle. No fights occur all month. Next month, their morale plummets to Very Low, and the only battle is an Ambush scenario against a couple of Wasps, one with a totally incompetent pilot...which is a one-sided turkey shoot even for my green pilot in a Locust. Three months into the campaign, the pirates rout, and I sit there for the rest of the contract with a total of one more random encounter, which turns out to be roughly the same sort of "clubbing baby seals" act as the first. 9 months, 2 minor scuffles, 4 kills between 2 pilots and none for the rest of the company, and my Administrators have gained something around 40 points of experience and gone up two levels. Ridiculous. If I had set the weekly gain to zero, they'd spend close to a decade to go up a level based on just the low semi-monthly chance for an experience point.
