9.15 - 9.18 - Smaller patches, focused on stability and lower scope balance work. We'll be looking to avoid things with big systemic impacts here in particular (e.g. reworking items, changing strength of different positions significantly relative to each other, changes to objectives etc).

This is all from the perspective of balance/widespread meta impacting work. New content like skins, champs etc will continue to release as usual.
Not taking a stance on when Panth's coming out either way but:
