Should I main Masteri Yi, Udyr, or Sona.

Master Yi is crazy OP with Sated Devourer atm (mostly at lower elo solo queue but great regardless), so if that's what you're looking for as a jungler do him. Udyr is more of an objective control freak with his fast and safe split pushing, and also apparently good at early counter-jungling and low level solo Dragon, so it depends on which style you like.

Sona is not widely considered that great atm, but she's a strong lane bully and an easy support to play. If you like a lane bully support, she's your gal.

Had to vote stfu nerd, but in all honesty depends on your playstyle. Of the choices I'd pick sona.

Sona

Main Veigar

Udyr because you can open d gates and your team will bow down to the godyr.

And you NEED to have SGU if you plan on playing him.

idk guys

If you don't want to go through so much work or hate, then try sona.

Udyr is great right now with Devourer. You do great damage and can still be super tanky.
