Master Yi's Q (Alpha Strike) 
makes Jungle creep go into stasis and continuously heal... making it near impossible to kill them. If happens when he disappears.
When he disappears during his alpha strike, the main monsters(the one that offers the buff) freezes and heals rapidly... continuously , until he uses alpha strike again. A major set back for early game jungle...
Maximum Morde2 votesRemove Yi's untargetability while alpha striking and they wouldn't do that. Please fix our poor Yi and help him Riot!

KelleraSW1 votesThat happened as well when I was playing 
yesterday when I was taking blue buff, but the difference is, I was standing still in front of it auto attacking it while spamming my skills.

jungle just today and bam... Blue Buff wouldn't die no matter what I did.
ConsumingDarknes1 votesYes, this happened to me today too, it is bad for early jungle, and for the game in overall.
