A lot of players were relying on the early Warding Totem to protect standard invade paths, which ended up preventing meaningful aggression. We like that invading can be a team strategy, so we're hoping this helps out. Plus, lowering the swap cooldown for trinkets should allow for more flexibility.
I really don't like the language they use in their patch notes. Saying stuff like "We hope" lends more credence to the thought that Riot has no idea what they are doing.
