Once you complete single player campaign, you only have to play practice mode 3 times to make that amount of money again takes about 2 minutes ^_^

Not that it matters coz his rank is too low... should probably have looked at that

Rank... lvl... same thing ^_^ His game level is too low to have completed single player campaign. I was just saying once you've completed it, it's easy to get your gold back by farming the practice mode, so there's no loss in money buying kits really.

I then realized his level was too low to be farming practice mode, so he's just buying kits from money won in battles (which I've found less common among lower levels players) to improve rank. Nothing wrong with it just gonna be a pain to build a higher level mech
