You want big points? Play Islands as GDI and hit the Hand of Nod with your mrl for the entire game. Saw someone get 910 ladder points cause he just kept shooting and never had to move an inch. Sure it's boring as hell and personally I think it's lame, but it doesn't involve any teamwork, skill, or general thought to pull off (perfect for a great many people).

Myself I stopped playing for points while still on the MP demo. No challenge, just shot mammoths (in green life, no ones mentioned that yet) with a Sakura and I got MVP every time. Now you'll hardly ever find me leeching points, I'm either shooting down apache's with Havoc, vandalizing flamers and stealth tanks with a PIC, or having sniper duels (I'm notorious for this on Mesa).

I'm not knocking on point-players here, whatever grabs your fancy is fine. We play to have fun right?
