4v4 Practice Mode - SE Please

[Tillen]

Is there a way to, or can SE please implement, practice for 4v4 Ranked Feast? I feel as though 8v8 and Frontlines cannot adequately prepare folks for 4v4. Even a hall of the novice that has tasks like: What to do when being CC'd as a healer, focusing the same target as your co-DPS, CCing a healer, and when to pick up stacks. I think it would help out a lot...maybe. I just feel bad as I try to learn as a healer and end up ruining 3 other peoples' run.
Before 4.0 is was quite simple to Feast and learn on the fly however, I feel with the new changes, the margin for error has decreased substantially. Just as I think I've got it some DPS fails to focus that Tank with 8 stacks, or Tank LoS me and doesn't CC the other healer and all is lost. It is very frustrating especially at the lower tiers.

Implementing a way for unranked, bronze, and even Silver players to train will alleviate the stress that plagues Feast devotes.

And yes, I'm aware the "git gud" comments are incoming but even when I heal everything appropriately it only takes one screw up by someone who doesn't care to screw the match for all 4 of us.
