Didn't pick tanky DPS characters like udyr and volibear? Well enjoy the next five minutes as the other team bullies you out of the alter and jungle and then snowballs you to defeat.
Bro, I just went up against a Teemo, a Darius, and a Katarina.
We were Kha'Zix (me) Wukong, and Shaco. We fought back and forth, but won.
Just because bruisers or altars exist does not make a game snowball-y. You're not looking at what make the map good, just being upset over the lack of wards and map awarness. If a team is beating you, find a strategy to beat them. Don't blame Stealth or Teemo for existing.
