Positive comments about 4.11? I'm positive the AI is fake, and team TD is secretly flying it themselves.
I've just set up a nice little one-on-one in the QMB between me in a P-39, and a 109 E - starting at 3000m on the Slovakia map. Got myself nicely trimmed into a cruise, rads open (I'm paranoid about overheating since the patch) when the 109 appeared. So what did Emil do? Bimbled past, as if he hadn't seen me... Didn't want to fight, eh? I gave chase, trying to sneak up on him from his low six. He know I was there though, and proceeded to start a vertical/horizontal turning fight, which I was winning until I went into an inverted spin.
Heaving back on the stick fixed that - I was now spinning upright instead.
Some frantic stick-stirring somehow got me out of it - at about 1000m, over tree-covered foothills. Emil, who'd presumably been watching and waiting, took advantage of my plight, and zoom 'n boomed a few times, before we got back into a turning fight. low over the trees, I nailed him eventually, but only after running out of cannon ammo, and almost colliding with the treetops. If Emil had been an online pilot, I'd have given him a salute - so instead, I salute TD, and in particular, whoever is responsible for adding the extra 'I' to the AI.
P.S. 'average' AI - I'll have to try the same thing against the ace setting - I've a feeling that Emil will be reporting back on the result.
