When I play Infantry I take more damage from team mates mindlessly spamming swings in battle than from friendly horses or friendly archers.
Just today I was riding past a guy, he was on my left and slightly further up the slope we were on, he was moving away from me and I was steering clear of enemy pikes to my right, I wasn't close to him, but he suddenly jumps down the slope right back into my path, I tried to turn when I saw him jump but it was impossible for me to avoid him as he literally jumped right infront of my horse, then he got killed and blamed me.
He blames me for what, for being on a Horse?. Yeah, I pay the upkeep and the skillpoints to ride it, if you are going to jump directly into my path when I have tried to give you as much space as I can and not interfere with your fight, without putting myself in danger, I certainly am not going to take any blame for it.
I'm also not going to ride around in circles in the few open spaces on certain maps, I stay aware of my team mates around me, but being a good Infantry player requires awareness too, because if I was an enemy cav he would have been just as dead. You can't blame friendly cavalry for everything, especially if you throw yourself infront of speeding horses and expect them to be able to steer out of the way everytime. In many cases it's neither parties fault, but the infantry player chooses to blame the cav player simply because of how the horse bumps him down, even though the Cavalry player did his best to stay away from the Infantry player.
It's the same idea of when you are having a melee fight, you and one enemy are face to face swinging at eachother, then a team mate thinks it's a good idea to run from behind you and past your side, causing your side swing to hit him before you can even see him and either hurt him or glance off of him. If you hit your team mate and hurt him or kill him he then blames you, even though it was his fault for being a stupid twat, but if you glance off of him and die because the enemy hits you during the moment you glance off of your stupid team mate, he doesn't think he has done anything wrong.
They are the kind of idiots that make it nice to play Cavalry, because I don't have to deal with them and quite frankly, regardless of the whines about cavalry, I will continue playing it and I will continue going into battles to kill enemies.
