PSA: With Cannon Minion changes, Minion Dematerializer is very, very powerful atm.
They are a mini objective in lane so if one opponent has this rune, they have a huge tactical advantage over the other if they do not. If one person can just boop the minion out of existance, they are free to harass and deny the fk out of their opponent, who cannot retaliate or they risk missing the minion. Cannon Minions are worth so much more now that if you start missing them, they will really set you back in gold.
It can very much turn the tide in an otherwise shitty matchup, and make a snowball matchup that much more difficult to prevent.
Just saying... :)
