That additional slot just doesn't cut it...
Therefore I believe there needs to be another worthwhile bonus for going that extra mile and there are several i can think of.
Examples:
A ) Give the Master level a 2x bonus on the Elite skills as well - even if that means halving them in the first place!
B ) Give a 4x bonus to Basic skills - even if that means quartering them in the first place!
C ) Both A + B
D ) Give the Master level a slight CBills Bonus, maybe 5-10%
E ) Give the mastered mech a higher GXP turnout, like +2.5-5% (so 7.5%-10% in total, up from the normal 5%)
F ) Convert additional - currently useless - Mech XP into GXP automatically at some rate
Personally i would prefer A - C because they don't cut into PGI's business model - even though these useless Mech XP are a real nuisance.
