Sometimes you stick with a hero and thanks to these orders you try another one. When we had to use a vanguard hero I picked Kensei, always thought he was slow and ugly but he surprised me and now I think he's pretty good. I was unlucky through both closed and open betas to fight against a good Kensei. The same goes with the game modes: "in dominion gear matters so I don't like it" bah grow a pair ffs you deserve an Archie's slap: https://youtu.be/2N7NTHSdquw
I would agree that allowing Orders to be completed in either Player vs Player or Player vs AI at the user's discretion would be the best compromise.
I had a lot of trouble during the Open Beta completing Elimination/Dominion matches due to people leaving upon death one after the other and causing the match to error. Not sure if I was alone on this, though.
Some of my friends need more practice, too, and I don't think it's fair to force less experienced players who may or may not have zero interest in PvP for whatever reason to play it just to earn a decent amount of money each day. We are paying for this, after all, and I think it'd be fair because then everyone gets to play what they want without being hindered from earning money. That- and people who aren't as experienced and are training on AI don't have to impair teams of people who have been playing PvP for a longer time just for an Elimination/Domination Order.
I would say if it doesn't harm anybody, letting people pick PvP or VS AI is fine.
