That is very subjective. For me it’s the second strongest Kerillian melee weapon, after Glaive of course. Yes, you have an objective argument
but it is falty. 2h sword’s charged attack deals cap damage (256), easily one-shotting CWs and wrecking bosses. So it only gets better on Shade, cause Shade can compensate for its biggest weakness - armor damage.
It always did very low damage with shade ult. Shade ult multiplier is based on crit multiplier, and 1h sword has one of the lowest. Btw, you can get +% crit power and increase your ult damage because of this mechanic.
Also I think it’s vice versa: 1h sword is actually great at dealing with elites by itself. It’s biggest weakness is dealing with hordes, and Shade doesn’t help much with that. 5% AS kinda help, but that’s not enough.
