Thanks. I appreciate it.
Make sure to buy upgrades based on what style you play. I don't like RA much, but it's useful in world games and high funds. I see you like to use GW and MoS, so you're probably into stealth. Faster infantry helps with all strategies so I'd buy that first (Assuming you got air transport capacity, transport capacity, subs, marines, and militia before), but then you could move to faster marines then cheaper marines if you're still into stealth. However you should give strategies such as PD, SM, NC, and IMP(looks like you already play it) a try. They're all different styles and could suit you more, and if you really like the game and want a general/general upgrades/more strategies ( a lot of other things too) you could consider getting premium which unlocks 5 more strategies, 3 of them great and 2 meh.
