Making baron calls
If you are lower level than enemy jungler AND/OR the enemy jungler is simply alive and you aren't ahead in levels, do your favors a team and yourself by not looking like a moron... IS NOT a good idea. Can't tell you how many games are thrown at this ELO from utterly bronze tier level baron calls that a bronze player can accurately say "Wow I can't contest that stronger smite 2 lvls ahead."
With that said, if you aren't the jungler; don't tempt the jungler into baron when he doesn't want to. You don't NEED baron to win. My God honestly the only time you NEED to baron is if the enemy team is on it.
Honestly I forget who but I remember one famous streamer who used to say don't make baron calls with enemy jungler alive even if they are equal level (though that was during season of god tier combo smite junglers).
