YES!!! FINALLY!!! DUELING!!!
I'm surprised nobody has posted anything about this yet, but I'm pretty excited that they are finally implementing this in patch 3.4! If wanting to keep PvP alive this would be a good step because now people can practice while waiting for queues so they are more confident in fighting and also people spectating can provide tips and tricks. To improve players overall.
But the main reason I've been wanting it is so I can smash my friends in 1 vs 1 duels and show them who's boss :p
What about everyone else? What is your reasons for wanting dueling to be an option?
