I know it's been a while since I posted this comment, but I would like to retract my position. I understand why there are no rewards for a pay-mode, and I can't argue against that reasoning. This mode is not for players like me. It wasn't meant to be. It's pay-to-play with no rewards to keep players like me out of it so the casuals have a place to play against other casuals. I understand this now, and it makes sense. If a Rift run lasts for one month, then players doing their dailies in Rift mode can have as many Rift runs as they need, and at the end of the month still have gold left over to buy packs. I call it a pay-mode, but really it's more free-to-play than the regular game if all you play is Rift. My only concern would be it not generating enough interest to maintain a player base, but then that doesn't really affect me, so I don't really care.
I'm not losing anything by being excluded from this mode that I didn't even know was coming out until the beta went live, so really, any criticisms of the mode by me can be ignored.
Side note: I didn't keep playing my free run. I stopped playing after 6 games. It's not that I was really bored, I just would rather play Ranked mode, and I guess that's the point, isn't it?
