Leave his active R as real invisibility.
Make his passive evolved R camouflage.
imaqtpie, Cowsep, and others will still say that the uncounterable R invisibility is bullshit - because it is - but at least he wouldn't be able to pass by every control ward on the map without using it.
and also make Duskblade have a hard cooldown of 10 seconds before you can get the bonus damage again.
I agree. His evolved R's passive is meant for creative gank routes & catching enemies by surprise, like 
. Invisibility is designed to be used in-combat to confuse the enemy. No reason he shouldn't be spotted by 
. Why else did they even change Stealth at all then? Why change Rengo/Eve into Camou if K6 essentially is a better Eve?
Just put in a giant boot that chases him around the map and eventually steps on him.
Just remove it. Invis champs shouldn't exist.
I would rather they just revert it to what it was pre-rework. Sure, the old evolved R could be inferior to everything else at times, but it did feel like an option, and I always felt it was the most balanced of the then-existing stealth mechanics.
The 'free stealth for walking into a bush' thing has always felt... wrong to me.
I like the idea of the passive part of his R being camouflage not stealth, so red wards can spot him, and he can't just bush juke you 14 times for free. I also feel like perhaps Duskblade should have a... Tear-like limitation system? Make it so it can only activate on the same target twice within 8 seconds. There's no reason one champion needs to be able to proc 200 physical damage on an auto that already gets another 200 magic damage from his passive time and time and time again. Ever since that change to his ultimate, everyone has evolved his ult first and I very rarely see Q evolved, if at all. It used to be Q, E, then maybe R since it allowed an extra use of invisibility. Now Q doesn't get anything but a CDR buff against secluded targets and his R basically says 'Hey come here with Duskblade first item and get a free ~900 damage in a single fight anywhere near at least one bush.
make pink wards great again
There was a discussion about this on NALCS Lounge over a month ago. They basically said that, while this would be a more balanced solution, it would also lead to a lot of confusion, since you're having both types of invisibility in one ability.
I have an idea for that think Talon's E wall duration so they can add same thing on every bush.
another great idea by someone on the boards that wont get any attention, cause riot doesn't like good ideas
I actually like that idea.
maybe
You realize that if you enter a bush that has a control ward, you've been spotted before you enter stealth?
