By far the easiest way to get kills. Get a friend. Put some C4 on a wraith cloaked flash. Find some infantry. BOOM! XP in your pocket.
I love beep beep, Jeehad Jeep. Used to do it all the time in the Battlefield series, where the hitreg was reliable enough for it to work most of the time. Pity it tends to fail so often in PS2. Get those 2/2 MBTs. It's like 800 combined XP for a guaranteed one-shot kill with two C4 strapped on the front. It's a pity it takes about 3 C4 to take out a Sunderer, or you could roam around, taking out entire squads in one blast.
Overreacting lol, weapons lock rofl. I've been trying to do this with ESF but physics make it very unreliable. Heh @ Legged getting hate in the chat.
