Dream Flight sends the evoker flying in a chosen direction, hitting allies along the path with a large up-front heal and applying a 15-second HoT to each ally that was struck. The HoT stays on the players that were hit, it does not follow the evoker after the cast.

The up-front hit is the bulk of the throughput; the HoT is a smaller follow-up tick.

Tip the Scales buffs HoT effectiveness, so casting Dream Flight during the 30-second buff is technically an HPS gain on the HoT portion.

While flying, the evoker has limited control and can be vulnerable to mechanics on the path.

Assign it onto damage windows where the raid is stacked at cast time so the up-front heal and HoT land on as many players as possible. Once cast, the HoT continues to heal even if the raid spreads.

Do not assign at moments where the raid is already scattered, since fewer allies in the flight path means fewer hits and fewer HoT applications.

Conditional CDR:

Temporal Burst (Chronowarden) gives about 4.5 seconds of bonus cooldown progress per Tip the Scales cast on everything recharging. Flow State can add up to ~6s/min more at 2 charges, but it's currently off-meta. Worth a few seconds of planning slack.
