"Generally going for safe changes this patch so we can target accurately. There's a decent amount of unknown, with 12.16, 17, 18 having no Pro Play exposure, but we're relatively confident we'll be in a good spot post these changes. Udyr changes are buffs to DPS and nerfs to Tank" - https://twitter.com/RiotPhroxzon/status/1569829428280303616
