Planetside 2 is actually a very underrated MMO - It had the largest and most epic battles I've ever witnessed in an MMO. We are talking about 500+ players with different roles in the team. Some players just logged in to be the transporter - transporting troops to different bases, every battle wasn't just about numbers, it was also about tactics and wars for control of different segments of the map raged on for weeks/ months. My tactic was always relatively simple - get an aircraft, fly right into the center of the area with the most enemies, jump out of the plane right as it crash into them and take down the rest while jumping from cover to cover so that my team can flank them from another direction. The funny thing is it worked about 80% of the time with the other times being of course not jumping out of the plane at the right time (really embarrassing) or the plane gets shot down before I could execute the tactic.
