Double Smite Strat is broken

Lately I have been seeing a lot of this double smite strat showing in ranked low elo games. This is a strat that allows the duo junglers to level faster than a solo jungle because they can clear camps faster and gank multiple times over and over again. It does not matter how well you do or don't do in your game, if you are against this you are guaranteed a loss. This is a strat that should not work and allow such an easy way to out-level and out-scale. The duo jungles are in most cases leveling faster than an adc and support staying in lane the entire time and getting kills. I would hope you would stop this by allowing only ONE person to have smite equipped. It would permanently fix this issue. Allow people to trade jungle, but make the game lock it if one person already has smite equipped. The way the xp works with this strat I feel was not thought out or was overlooked in some form. This gives a double jungle too much of an advantage especially if it is giving them more xp than 2 people sharing xp in a lane.
