I dunno, crs and clg (na) both had the best performances they have had in awhile. I don't think any of it was roster issues.
On to diana though. Yes she is a terror in the new jungle. Fast clear, very safe and has decent ganks. I think she's still better in the mid lane, but she is really good in this jungle. Apparently mundo is god mode right now. I haven't had a chance to try him though.
