Why?
Cause I have many friends in my account sharing an epic monster and I dont want them to think
" hot damn, I want a legendary too" 
I wasn’t able to get my hands on a legy until way after I had finished the game both online and offline. The best se in my opinion are time/cravers and death/thirsters. But there are epics that you should look out for such as duplicate/stun revenge, bombers, and setters such as sleep/stunners.best in game monsters are stun/death revengers and stun/accelerate all mons.I myself don’t mind legys that much anymore as long as devs at least buff in game mons which the recent nerfs of stun bomb makes me think otherwise
