ninja don't do 123, you are far from the reality...

the ninja have a cycle quite unstable because we need to replace one dot in combo every 18 second, where the other one is out of combo and have a duration of 30 second, more important the mudra that can mess up the cycle because of the lag. normally a 3 mudra skill must take 1.5-1.7 second but with the lag it's often over 2.2-2.3 when our gcd is often under 2.1.

other point the ninjutsu mechanic is the only mechanic that can failed! no monk nor dragoon nor summoner nor black mage nor even bard have a skill that can simply fail and loose a 20 second CD.

ohh before i forget, we do have the biggest cycle of the game.... far over the one of the dragoon, our cycle is 60-70 second. the time needed for refresh Huton, only the ninjutsu take 11 imput (3 for raiton, 4 from huton and 4 for suiton) we use 3 type of combo and i don't talk of the outgcd skill.... seriously, i play both monk and ninja, monk have the easy way in comparaison, the positional fight of the monk are extremely simple (if the tank is not a moron)
you navigate between 2 combo, one for the side and one for the back, depending of the time for the dot you make a small variation for the end of the combo...

seriously monk are still the best dps out, if you are beaten by a ninja, you need to train more dude!

ps: next time before come talk of a jobs, try to play it a bit....
