Once state rewind for ballistics and missiles roll in, I'll have no more issues playing light mechs with the lag shield advantage removed. I'll probably need to buy more mechbays soon though.

If PGI releases enough items that need GXP and combine their double XP weekends with the conversion promo, it might be a decent boost to revenue if done at the right times. Right now the modules are looking better, but we probably need a lot more options to unlock before the GXP train starts rolling.
Also consider using GXP for other things like merc corps, CW, and others. It's something that free players can earn and can be monetized with conversions and premium and based on how the Coolant module issue was addressed, it appears to be a very acceptable option for the majority.

Well, off to grind that last basic efficiency on my Jenner~
