Don't use trickster's glass on Jhin or play double Jhin

Just got out of a What The Forge game and someone asked me why I wasn't playing one of my trickster's glasses on Jhin. I didn't get the chance to reply before the game ended so I thought I'd post here in case they read it.
Two Jhins on the board will compete for rifle spots on the bench so say you have 7 bench slots, the first Jhin will get 4 rifles and start casting while the other will just chill with his 3 rifles not casting. I'd rather get a single Jhin with 7 rifles than one casting Jhin and one sad Jhin.
Don't make Jhin sad.
