One time, there were an former infantry officer from the 6te in which i was a member before as well. So, he has been my officer.
I had my cav regiment running for quite some time now and he was part in an own cav regiment for about 3 weeks.
He contacted me and said that cav is pretty cool and thought that he now is pretty good with cav and also his regiment is pretty good against other cav regs. While our chat was going on he invited me for a duel on his server. He really had some confidence back then, but the story weren't funny if the duel were fair or something. By now he was a bit fustrated and stopped our little fight. He said that he is really surprised loosing so much, but for me, he also sounded like he learned something out of it.
Long story, short conclusion: Cav is easy to learn, but hard to master... and you really have to master it in some fields if you want to rek infantry.
Seriously; to all you funny infs here. You can't come to a conclusion about cav by playing it once in a lb, neither can you with other classes.
Back to topic: Almost every class here is unrealistic, but from my knowledge and experience pretty good balanced. Also the devs most likely won't change anything, so why even talking about it?
