Best class for party contribution - WL, BM, or FM

[Noellessa]

Hi all,

Sorry if this is the wrong section, but I was wondering which of the above 3 jobs (WL, BM, and FM) people think contributes the most to group play both during leveling and endgame.  I love WL since it is fun to play and gives the SB buff, but I also like the action-y combat style of BM.  FM just is an all out dps monster and mobs seem to just melt no matter what I'm doing (though really squishy compared to BM, it seems).  Just looking for some ideas as to which job I should focus on if I want to both contribute a lot to parties and be needed.  Thanks!

WL is by far the best party buffer. Followed by SIN and KFM
