If we're talking Kroguard, then his primary weapon is the Omni-Blade. If the majority of your kills aren't from melee, you're doing it wrong. BC is primarily important as a rapid method to close to melee distance.
MRAWRRRR!!!
True Dat.
Which leads to the next logical question: is melee characteristics closer to a weapon than a pure power?
Melee is somehow a hybrid between weapons and standard offensive powers
Some points :
1) it works through shields and barriers (in contrast to standard powers -( exception with AF, Reave)
2) can be increased in some classes in passives, offensive and gear.
3) is not affected by shieldgating like weapons
4) is not always physically close (see demolisher)
5) is not always offensive (light melee with volus renders a volus invisble - refer to volus double cloak no/low cooldown)
6) the paladin melee omni shield strength can be boosted with the cyclonic modulators
7) useful for many bypass exploits collector adept cooldown, reload cancelling , smash dept etc.
It's probably the halfbrother that's between the large shadows of powers and weapons- if not made famous by the kroguard (and notorious for memorable sync kills in gold> for pugs that newly migrated from silver valley)
Probably the most unsung hero of the game...
