So, I would like to explain the rules of caving that have been developed on NA since 2010. While these rules are unofficial they have been preserved through the traditions of NA cav though the years and by us traditionally been followed.
1) Always give the senior cav right away.
a) This means that you should always be warrey to give the more senior cav the right of way.
b) This also means that the senior cav is aware of you and will stay out of your way as well.
c) In the event that two cav collide all care should be given to ensuring that both may escape without substantial harm.
2) In 1v1 jousting, where the challenge is clear, it is unprofessional to go for killing the opponent horse instead of the rider
a) Traditionally, cav have shown great respect for each other and as such it is a great sign of disrespect to kill the horse instead of the man, as following this will cause him to become dismounted demonstrating not that you are the better cav, but rather that you took advantage of the closer proximity of the horse.
3) A cav's primary target is enemy cav, followed by enemy archers, and then infantry.
a) While opportunistically this ethos is not always viable, it severs the best interest of the class to follow this rule as pubic opinion has a substantial impact over the viability of it.
b) Cav should always have their fellow man in mind and act on behalf of their team not just their kd.
4) Team-bumping should be avoided at all costs
a) Cav is a support class at its heart, and as a cav we are advocates for our teammates, thus it is against our own interest to not represent theirs.
b) Thus, even if kill can't be achieved, it is always ideal to bump an enemy so that a fellow infantry can get the kill as that is in the best interest of the team.
5) If you unintentionally kill a friendly cavalry unit's horse, it's polite to dismount and offer your own horse to them.
a) The rider should remedy his mistakes when he is at fault.
If I think of more rules I will post them, and please leave your own!
I would also like to thank the Devs for making heavy cav viable again with the new xp/gold. In doing so cav can once again be a substantial counter to archery while remaining vulnerable to players able to focus on challenging us.
Overall, the current balance between all the melee classes, range and cav is most impressive and better then I've seen it in years.
