It would be a buff because he'd always be able to use it after he dies and his passive activates.

Right now he gets locked out of using it if it wouldn't finish before his passive ended. But this time he'd always be able to launch as many Qs as he wanted and then hold down R for it to do the max possible effect in the teamfight. Even if it does a lot reduced damage then it'll still be better than nothing. And 5 Qs and a half charged R would double his teamfight damage compared to 3 Qs and a regular R.

And also it would make enemy counters to his ult harder if not impossible to time. Spellshields only last for 1.5 seconds while his ult can possibly channel for 3. Zhonya's 2.5 seconds is the only one which comes close.
