Since 3.0, Range jobs overpowering Meele jobs on Frontline has become an issue with the 3.0 simplified PvP system. It has becomes so problematic that nearly Meele jobs are nearly push to their extinction. You will only seeing Tanks Ranges and healers with one or 2 veterans that know how to counters

This issue is finally resolved after 4.5 when SE increase Meele survival ability without actually nerf Range jobs.

Your suggestions would not make any sense as it is not the action is weak, it is all Tank and Meele have 30% damage reduction. It has nothing to do with balancing.
