Okey I suppose that there has already been a lot of threads of this but since I didn't find any I decided to post this because I really want to know.
Are you planning on making a team ladder where you make teams or clans and search for opposing teams with an automated search system in-game?
The reason that I'm asking is because it will be the most effective way to surpass dota which lacks this.
The main reason why dota is lacking this is probaly because an automated search ladder will need lots of dedicated servers.
However, this is not something that HoN lacks and you have already made a PSR ranking system so making team or clan ranking systems shouldn't really be a problem for you or? ;O
An automated search ladder will not only add a fun way to play HoN competetivly but also help clans find even opponents which will help them improve.
If the ladders point system is working well, then everyone will be able to play against a very even opponent by just pressing a mouseclick.
Obviously the mode for the main team or clan ladder needs to be captain mode =).
