These are the things that need to be fixed right away.
Pole healing 1.1: People can heal the pole while being dead, as long as you're near it. That being said; it's almost impossible to get a fair winner when people keep healing the pole.
Pole healing 1.2: healing pole is much too easy. There should be a limit on how many times you can heal a pole per round (3 times or something is fair)
Revive: revive should be fixed. It's the water tao's signature skill, without that skill you completely underpower that entire race.
Wall jump: there has to be an sollution for people who constantly walljump or run (with their steeds) through the gate.
Lag: and finally, the lag. It's not yet sure why it keeps lagging with only 30 - 40 people in the server. If 40 is the maximum amount of players, then we really have a big problem.
