A buff Idea to Rift Herald

I don't know what is Riot's stance on Rift Herald's current power level, so I don't know if they would be interested in doing this, but I believe that Rift Herald is to easy to kill 1v1 for the power it gives. Considering how it was made, it was supposed to be taken by two people (one tanking the herald while the other hits the eye on it's back)

My suggestion is simple,if possible, don't allow the herald's eye to open if he is fighting a single person, only allow it to open if he is facing 2 or more people.
