Conquerer is a Rune

This is not a rant against Conquerer but against every other one. When Riot introduced new runes, they wanted them to be effective and Conquerer is actually effective. If you don't take it you will be losing incredible amount of healing. But if you missclick and get aery instead of comet then yes you would lose some amount of damage but it is not big of a deal to change the outcome of the game. I think Riot should focus on making the runes so that they are game changing for the champion. What's your take on this?
