I don't understand why 1900 players like to play 1800 players and just tryhard tower them and destroy them?

Like don't you have anything better to do other than annoy the fuck out of players that are lower rated than you? If you're playing vs someone of a lower ELO then at least make it a fun game for them somehow. Getting stomped, and worse, getting stomped by mass towers, is not fun at all. What enjoyment do you get out of it. I don't understand.
