TFT patch 15.4 notes, release date, and details

At combat start, ranged champions now properly respect tank-targeting tiebreakers. To help with this, we’ve updated ranged champions to target before Melee champions move; this should prevent ranged champions from targeting a wrapping Fighter that would normally be protected by their adjacent Tank.

Fighters
No longer gain 8-20% Omnivamp per stage.
Now gain 5-30% Attack Speed per stage.
Stage 2-6: 5/10/20/30/30% Attack Speed.
Some Fighter’s base Attack Speed have been modified to compensate.
