I don't know what the intended experience is supposed to be, but I don't think there's any getting around the fact that aoe is king in large scale pvp where you have that many people involved.
Truthfully, I don't really enjoy Frontlines myself. I view it as a grind to get through. I got mahjong master, I got my rival wings achievements done, now I am 1300+ wins into Frontlines and pushing. I don't really enjoy pvp, but I am an achievement completionist, so it will be liberating when I can finally say I am done with this content.
