Final Attack doesn't exactly do the final attack, it's just a chance to do bonus damage via extra hits that don't even scale up (unless you have enhancement nodes).
It'd make since if it were like Mortal Blow, where it only procs after an enemy reaches a certain hp ratio but Final Attack occurs at any ratio and is almost never the "final" blow.
Additional suggestion: rework Final Attack to be a skill that procs where an enemy has less than 20% or so HP remaining and deals damage that scales up based on character's level.
Decent rate would be around 150% damage + 3% damage per character level (up to 750% bonus skill damage (not final damage)) that also has node enhancements of 2% final damage per node level. Classes with Advanced Final Attack would have an extra line but final damage reduced by around 35%~40%.
Not sure why maple classifieds was deleted along with everyone's posts when it could have easily just been renamed but I'm buying maple points in transactions of 270 per 100 maple points via the Meso Market. Hopefully I will be the receiver through this anonymous trading service as I'm desperately trying to reduce the cost of using my own money to buy psoks for a character.
