There needs to be a few tweaks to the quest that require you ability kills, whcih means your super, grenade or special melee. All classes are fine, except one. Defender (Ward of Dawn) Example, the Exotic Sword Quest. The Fifth step, after the guardian and ultra kills, kill the hidden boss in patrol on the Dreadnaught and talk twice to Lord Shaxx (I think that is how it is spelled) you are required to grind 10 rare materials by RNG and 100% ability kills, depending on your elemental sword Now, if you were unlucky enough and picked the void sword with the titan, you need to get 100% ability kills with Defender. Problem is, WARD OF DAWN IS THE ONLY SUPER IN THE GAME THAT DOESN'T KILL YOU. So your stuck with the melee and greande which take forever. So, the this particular step for Defender should be like this Instead, if the ward of dawn takes damage, it counts for the "ability kills" that would make it fine. That, or make it while you have weapons of light/Armor of light/Blessing of light AND/OR you are inisde your bubble kills count for the "ability kills" step/ There is also other quest that are like. Example, getting the Defender emble has a similar step.
