Upcoming Assassin Rework?

As the group rework is coming soon after the rework, there are several champions that are in the list of champions with probabilities to be changed. I thought about this and as a very frequent player, I wanted to think if he was going to be changed. After some research, Riot is still thinking about it and I understand as making a change to this champion is extremely hard to balance. I have a suggestion as just making his stats a little better and making more use of his ult like making it easier to jump over walls with it. It took me several tries and I only got it once out of three tries. His passive is like a buffed talon passive so that should probably be changed. Any suggestions?
