Current State Rengar PBE Ult Possible Tweaks

Current Rengar ult as of the most recent patch makes him camo after a small cast time which i think camo and gives him movement speed, but the real problem comes from something else with ult in my opinion is that if you jump on the target nearest to you, Rengar gets full ferocity which on paper sounds great for rengar but, it interupts the ferocity from hop so you can only get at max 3 ferocity stacks and makes it hard to combo. You might be thinking its not hard to combo your just bad which is only half right (because i'm a silver ape) but it is hard because mid jump you are given the ferocity so you can just use it at the very start so the reaction for your ability activation is very small. It is theoretically do able to activate q at the perfect time then e w q again and then tiamat. But using that combo is pretty much impossible because the e cast time will haveyou throwing your bola on the ground so all the ult does is make your burst weaker unless of course your very fed in which case it will make the burst absurd because you will just empowered in mid air if your good or when you land just delete him. Using just empowered q in the air is hard but very do able with practice but i personally think that they should remove the full ferocity and replace it with true sight of multiple targets instead of just one. There is something wonky right now where you can see multiple targets but im not for sure how that works but it is in the game ive tested it in practice tool and it seems like its meant to only see one but you can see multiple so it might be a bug. Bringing back the damage from the patch before this is a terrible idea and just adds really easy burst damage that is unfair. They could maybe try giving rengar full ferocity in stealth but i think that would make his burst way to strong. Another idea i cooked up was that maybe after hopping they could give him a movement speed buff which would be like an escape for him bursting a target if you mix that in with his empowered ability speed and youmuu's. If you have any other ideas about possible changes to ult or if you think i'm wrong please leave a comment, thank you for reading.
