While I agree that DMG dealt should still generate CE....
RUN's problem is that it has the physical durability of a wet paper sack. Not that it can't generate enough enmity.
In terms of enmity generation, RUN is definitively superior to PLD. RUN has a ridiculous array of enmity tools. Tons of JA, all with notable CE values. And two very good native enmity spells, flash and foil. And foil, being self targeted, generates enmity for every mob on the hate list.
Code:
Action CE VE
Elemental Sforzo 1800 7200
Vallation 450 900
Valliance 450 900
Embolden 160 320
Swordplay 160 320
Pflug 450 900
Gambit 640 1280
Liement 450 900
One For All 160 320
Batutta 450 900
Rayke 640 1260
Runes 40 160
Foil 320 880
Flash 180 1280
A RUN/PLD using sentinel could Cap CE(10k) in 10 seconds. Mind you, That'd take perfect timing with JA use. So lets say 15~20 for a more realistic value.
Of course, doing this requires RUN's SP, and a rather non standard sub. But even without /PLD, you could still hit 5K~ CE in the same time frame. And that's before accounting for enmity gear.
Furthermore, they have massive native fast cast letting them spam their enmity spells far faster than a PLD.
Wanna see PLD's enmity tool list?

Cover 1 300
Rampart 1 300
Fealty 1 300
Chivalry 1 300
Divine Emblem 1 300
Palisade 0 1800
Flash 180 1280

Reprisal 0 640
Enmity generation-wise PLD's only advantages are greater access to enmity+ gear, and sentinel(which is sub-able anyway.)
Although PLD does has a great advantage in not Losing as much CE. Both via taking less damage, and having enmity+ on already good PDT gear. Which is good, 'cause PLD has a hell of a lot harder timer building CE in the first place. A PLD that wants to build good CE, has to sub /BLU or /DRK for additional CE actions.
Also, using /war for enmity purposes would be really silly. Provoke is really not that good an enmity tool. And cures, while useful for survival purposes, generate truly terrible enmity these days. And RUN isn't going to lose and fast cast from changing subs. They can easily cap fast cast. +60% fast cast during vallation or valiance(which can be full timed via alternating) with 5/5 inspiration merits and Relic aug.
What RUN needs to be equal to PLD, is the ability to survive heavy physical damage. They've got the enmity thing covered even if they didn't melee at all.
