The game has always patched (or attempted to) towards competitive every year around Worlds. Hell they'll even indicate it in their patch notes that "This is the Worlds patch." I dare you. Look back at the .17 and .18 patches from the past few seasons. This isn't new.
Even still, just because Worlds is going on doesnt mean patches come to a hard stop. They're going to keep rolling out while Worlds remains on one specific patch, so I don't see much a reason to gripe, especially after 2 weeks when changes may or may not be immediately influenced by Worlds because hey, preseason is right around the corner.
This patch is literally the end of the competitive season. There's nothing else to focus on until January unless you want to blame high elo for patch direction.
