the solution for this is quite simple, make the blunt debuff affect to resistance to magic, saying that monk toss chi in his attack for reduce the resistance to magical damage behind... it don't solve all, but until more blunt jobs is added it the best solution.
it will open up more the team setup possibility.
i envision a rework, where we do loose our utility for become the counter part of the sam, when you team is more physical you go with sam, when you team is more magical you go with mnk. even if it don't make a lot of sense, it's the best way to solve a lot of actual trouble. while giving back a role to the monk.
because right now, please give me one reason valid to bring a monk in a group.... mantra? brotherhood? they are not strong enough for justify his presence.
ninja will bring more damage every minute, red mage buff is more interesting. in end everyone is better than us in everything we do... we don't shine in anything anymore. that why we are in this situation. we are not the top dps, we are not the most fast around, we are not the most usefull to the team...we are good in nothing. that the whole trouble.
before we did let it pass, because monk was decent in dps, but with the end of hw it was not the case anymore... and with the apparition of the sam, we did loose all purpose... and it's not utility we need, what we need it's to be a destroyer, what we need it's to be a powerhouse, what we was means to be from the start.
