Would someone please explain H2H to me? I don't know what that is..

H2H Or Head To Head
was a feature that HTC developed for both subscribing and non-subscribing members.
It was basically a server where anyone could host a room and that room could hold up to 8 players. Custom maps were used alot in order to have a better appeal to the 8 player crowd than to have a war with hundreds of miles of map with a 4 vs 4 side.
Its was a free feature that HTC gave to the community, but with repeated hacks, players abusing the system of the 8 player max threshold (If you look through the forums you could maybe find screenshots of 16-20 people being able to join a room), and constant problems with the players HTC shut the thing down last year, and it is never coming back.
HTC warned the H2H players that if it did not stop they would take it away, and they didn't listen and now its gone.
The End
