The reason they removed it has nothing to do With acidently clicking on a minion
Every "TRUE" Karma main is dissapointed with that change. Since it removes Minion denying which was just interesting since there was counterplay to counterplay to counterplay of counterplay. Seriously A Bad call from riot
Sometimes you would acidently save a minion
Lots of times enemy would react use 2X aa Or aa and then ability to secure a minion
Sometimes enemy would just Engage you since you just used a shield on a minion
Often times you would get ganked because of that agressive play
IT would often piss off enemy. I have had enemies so pissed of To the point where they took a fight with me they couldnt win. Only to find myself baited as fk since they just pretended they are mad and crazy so that the jungler has easy target
And sometimes you would deny a minion
Minion denying created so much mindgames to the point where enemy was counting on me to shield a minion o.o.
Not to mention there are other uses LIKE Capturing Better circles With R>E on minion. Speeding up a front minion so that he reaches enemy Turret and slows down the enemy wave which would give just enough minions who are behind the leader minion to catch up. Therefore you would deny a wave if an enemy is not in lane
What can I say Darkin Prime
Your reasoning and logic is so bad that you might aswell be on a Riot balance team
