Casual Breakthrough is *not* the actual answer to PVE fans
While some may enjoy it more than pure PVP, it is still ultimately a PVP mode, just with an incredibly limited map selection. This mode is clearly not supposed to be a mode anyone actually plays, it's a barely expanded version of Breakthrough Initiation to funnel people into actual PVP.
About two weeks ago EA_Shepard posted in the steam forums saying that EA is listening to PVE players who wanted a more casual experience, if this is EA listening then EA is deaf. This is, at best, barely a half measure with minimum effort. At this point the single best solution EA could have would be to bring back Coop mode from 2042 the way it is now. Let us pick a map and mode grab up to 3 friends, and play with reduced XP, it's all a lot of us were doing with Portal anyways.
