I very much enjoy the Titan engagements, as Pilot vs Titan and as Titan vs Titan/Pilot.
Pilot v Pilot has never enthused me in this game since day 1. I don't usually watch killcams except when I feel that I was lighting a guy up with no kill ... and based on those killcams, I *think* I'm seeing the same old lag issues from COD where the character I'm shooting at is frames behind what is actually on the server. Even trying to snipe pilots with the Titan's railgun was pretty frustrating. I tried aiming at them ... I tried leading them ... nothing seemed to work consistently.
