Welcome to the 5.10 patch notes - the one where supports get some lovin'. As we traverse the land in our diversity dirigible, we're still sussing out what impact the Cinderhulk changes had on the feasibility forest, so we've now turned our sights to sustain / utility-focused supports who have languished a bit in the diversity metrics. That said, rather than kicking all of the aggressive supports in the shins (except a small adjustment for Leona's E width to match the visuals), we realized we could probably introduce some new possibilities with utility mastery changes, sustain support item improvements, and some utility-focused buffs for champions more inclined to those ways.
Second thing - while we are still watching those Cinderhulk changes shake out, this doesn't mean we're going to be passive about the jungle in the meantime. We've seem some meaningful diversity improvements so far, but it's also clear that there were a few outlier champions who were just strong, so we're taking some additional action this patch (see: Gragas, Sejuani, Rek'Sai). Aside from some small follow-up for champions we adjusted in previous patches, that's the gist of 5.10!
P.S. Scarizard's out trying to find a better form of transportation than the diversity dirigible (frankly I think we've reached the pinnacle of design transportation here), so you get slightly less sass in the champion contexts. That's about it."
