Pro - Capable of dealing the most damage. The scanning ability is a must skill for hunting specific monsters. You get a cool AF hat
Con - Extremely pricey. Not too poplular in PTs. Not many people know how to connect bows or xbows WPs for a Renkei. Low defence. Now in terms of hate rate... Im not sure if the Ranger's damage is a constant hate magnets for monsters.
Both - Only real benefit in subbing is for hunting purposes
