Since DOA6 is a couple months away, I guess they stopped character rotations in 5 for good. For the last month they should make every single character playable though, but its probably not going to happen.
I don't think They need to go that far.... they should just keep the Rotation going... lol... I thought it was automated. Or does somebdy have specifically set the characters every week ? LoL... maybe that's why stopped it.
What do you mean they stopped it? There's still two additional characters unlocked on Core Fighters on XBone. You mean it won't change those two anymore?
Don't know, I mostly play the PC version with every character unlocked. Could be that they still have to update/decide which characters are going to be free for this week or something.
Maybe the full game will be reduced to a decent price for Steam's Winter Sale Day(s), especially with 6 coming soon, so that might be the chance you're looking for.
