Swains Q Timing

I main Swain :D Hes my favorite champion, and I have been playing him for a long time (As well as waiting for Dragonmaster Swain Fingers Crossed), and I just had an idea for Swains Q. I find it a bit frustrating that it deals ticks of damage once per second, but if someone leaves the range after, lets say, 2.9 seconds, the last tick of damage wont go off, so I was wondering if it would be cool to keep the same damage and ratios and such, but make the damage apply ticks like Fiddlesticks Drain (Every .25 seconds). I just think it would be a nice change :)
