I feel like am playing a totally different game, I'm a bit confused because most of what you guys said here is completely the opposite of what I've experienced playing as a lancer.
1) Heavy lance is great and does a nice damage, but most importantly, makes you able to 1 vs 1 against most infantry players. If you need 5 hits to kill an archer with it, you're clearly doing something wrong.
2)
I mean a lance cav, who should be the best at fighting other cav can't chase down other cav, because he will glance every time he hits another horse in the back, even if he has the faster horse
I had absolutely no problem hitting another cav player I chased down, as long as I didn't fuck up my thrust, same as when stabbing someone at close distance on foot. If you can get close enough behind another cav, hitting him with a lance isn't hard at all.
3) If old lance angle were back, not only it would be OP against infantry, but also completely ruin the balance in cav 1vs1 fights between lancers and 1h/2h.
Couching might be a bit too rewarding for the risk it takes, but I almost never used it as a lancer, because using normal hits was actually easier to aim. As an infantry player, I don't find it too strong as long as I'm aware of the incoming cav. And if I'm not, I'm fucked up anyway.
