I don't know who on the PvP team approved the concept that D2 could support the rift game mode, but they didn't do their homework well enough. Sorry, rift is not compatible with the game in its current state.
Rift on the new maps is literally perfect. The only real issue are the amount of rounds and the awful teammates that have no business playing PvP with the lack of reflexes, map awareness, and understanding I've seen spectating these bots. It's literally turning me toxic. I'm thinking Iron Banner rift should have a "prove you aren't a bot" form submission, a brief quiz on the rules of play, and how to hold a controller properly.
