This is what I do on retail wow. I log on, solo queue 2's skirmishes on my Warrior, brainlessly tunnel vision one target, win/lose and then log off. Random Battlegrounds suck and arena is reserved for people that actually care about it. Ashran used to be fun before the premades ruined it and the ridiculous damage levels of item level scaling has made it impossible to even enjoy the fights.
I've actually found skirmishes to be really fun. The only problem with skirmishes is that the gate timer is too long. The gate timer should only be like 15 seconds and both teams should be able to request rematches so games can happen quicker. There's too much wait time in this game and dicking around.
I'd also like skirmishes to be more of an instanced thing that keeps you in the arena zone instead of having to jump between loading screens every single game. It would be a much smoother experience.
