With the correct gear, warriors and druids can be pretty good dps. But more time and cost effective to play a ranger/rogue/mage, because with the same caliber gear it'll be better dps. My old druid back in carrow update got quite a few hrungnir kills and many 6* dl/aggy. My alt warrior atm has a mord kill as well, but using that same gear on a rogue would yield better results
Yes warrior can get kills but more likely to get carrow kills (mordy for example) with poison gear (halberd, helm, especially bloodthorn set).
I personally dont have neither hrung or mordy kill as a warrior, Im always on adds if they spawn, but I have a necro kill and all edl mains kills.
