I had created a thread about this in the actual Pugilist section of the site but seeing as there's only been a single post there since April 22, 2011, I'm going to have to assume they don't really check that part of the forums as much.
I'm making this thread with the intent of discussion and providing feedback based on the information we have for the Pugilist class and Monk job.
I'll start this off by saying no we don't have enough information to really say whether these changes will truly be good or bad. What we can do with the information we have though is speculate and come to conclusions of different scenarios. This is not a QQ thread or a ragequit thread. I'm simply voicing my opinions based on what information we have and allowing others to do the same.
Personally, I'm slightly worried with the proposed changes. Currently it is a bit difficult for Pugilists to keep their MP up through long fights even with Featherfoot evade MP. Now we have more abilities being introduced which continuously drain our MP.
Whether or not this is a good or bad thing hinges solely upon a Pugilist/Monk's ability to sustain their MP through a long fight. We now have Pgl Ability 4, Pgl WS 8, Con Ability 2 and Thm Magic 2 to help with this. If it is possible for a Pugilist/Monk to sustain their MP while using their skills and abilities that drain MP, these changes will be perfectly fine and the class will be quite viable in damage roles. However, if the above skills and abilities are not sufficient for Pugilist/Monk's MP needs, then we have a bit of a problem.
With the proposed changes, when a Pugilist or Monk runs out of MP they then potentially lose a good chunk of their damage potential. How much they lose is yet to be seen. However this means that they must then either attempt to generate more MP than they're spending or they must disengage from battle to regenerate MP. Again this is all reliant upon how well they can sustain their MP, especially through long fights.
So those are most of my thoughts on the subject. Please feel free to share your own below, though I ask that we at least try to keep it civil (hard, I know).
