Could champ select automatically change one your summs to Smite if you're jungle?
Too many times do people forget that they absolutely need to pay attention to their summoners if they move from one role to jungle. And then, when their team tries to tell them to switch to Smite, they're tabbed out doing something else, and not paying attention to chat. Thus, they go into the game with no smite, can't buy the jungle items, and the jungle instantly becomes 50 times harder for them to do.
Now, I'm not saying to lock the person who was put into the jungle role into only having Smite. Role swaps do happen, so, you could still switch out of smite if you so chose. Also, since people will likely forget to switch Smite out once they are no longer jungle (say they were autofilled), champ select will automatically switch Smite out for whatever summoner spell you had before you were jungle. If you already play jungle enough, and usually have Smite up, than the client simply won't do anything with you until you switch from jungle to another role, and then back to jungle.
Just a small quality of life thing for those people who DON'T PAY ATTENTION!
