It does help. These are some pretty lame rules to play with, but whatever. There is always TWW.
Only two real strategies I like in global as of right now. the small’s big world strategy (bomb russia with japan and easy take with germany g5 or g6) and the J1 DOW go for pacific victory. Everything else is too slow, it sucks.
If you are going to play a long game, TWW is hands down better, every aspect is just better. This is the problem with global, there are better games out there, unless I can expect lots of action and fighting tooth and nail back and forth for national objectives or race for berlin / moscow there really isn’t a reason to play global.
