Plugged Naegling in to compare against Savage Blade, KoR Excal edges out by an insignificant (8 DPS) margin. O3D is clutch.
Also realized I forgot about 10% crit rate, but that shouldn't be a huge deal and further favors Excal.
KoR has stellar skill chain properties though, so that's something to consider. KoR > SB (Light) > KoR (Light)
WHile I agree that that's a good SC, I have trouble imagining PLD getting TP fast enough to 3 step reliably without Mythic AM3. Sometimes it doesn't make it even with AM3. Could do it with enough mobs feeding you TP via shield mastery, though.
