It seems every update, melee characters in some way, shape or form are nerfed, while casters bask in the glory. Especially so with the nerf to improved critical, which lessened DPS outputs considerably.
So, I offer this idea for more balance, and fair gameplay.
1. Induce synergy with epic destinies and heroic enhancements by changing crit profile modifiers to exceptional bonuses with epic destinies. Divine crusader and legendary dreadnaught have gray areas for every melee class that has critical profile enhancements.
2. Introduce new, hard to obtain gear that modifies crit profiles with insightful bonus (or quality, or both - to compliment swashbucklers exploit weakness). Nothing too drastic, I think an additional +1 range or multiplier is plenty fair, and would entice more players to choose melee, instead of the insanely overpowered warlock who can wipe mobs on EE with one or two eldritch blast without touching Spell points. Perhaps this might lead to some over empowerment - maybe something to consider for next level cap increase
Or
3. Change Kensei's core 3 "Strike with no thought" crit multiplier with it's tier 5 "keen edge" crit range modifier. Allow both to stack with all other melee class crit profile enhancements. After all, the fighter -- as a classic - should be respectable in it's dps output and should compliment all melee archtypes (most classes crit profile modifiers are tier 5, so this would lock out at least overly extesive multipliers -i.e khopesh will be limited to x5 multi, 15-20 in a scenario such as kensei paladin + imp. Crit feat (would also be complimentary towards paladin's lack of do at this level - but honestly, we know paladin's do best pure vanguard so this mix will be a bit more unique). All other builds x4 multi, 16-20 ceit range at most with a khopesh. Similar profiles and mechanics on all other weapon types.
I'm not meaning for all of these to take affect together. Just separate idea bulletins to make melee more viable without gross over empowerment for particular archtypes
Just a few ideas, feel free to pitch in.
Sorry if this is in the wrong area. I'm new to the forums (but a veteran of the game at 8 years)
