Play 1v1 Custom Games to Practice Dueling

Of course this is not the same as playing 5v5 on the Rift but it's a hell of a lot more useful than playing vs bots unless you only want to practice jungle routs.

1v1 Howling Abyss games can be as fast as 10minutes and provide great dueling practice.

You will constantly face higher ELO players = more valuable mechanical practice.

The queue times are consistently fast.

You can duck out if something comes up, with zero punishment.
