Singed W should root after a few seconds
I honestly don't understand why singed W doesn't just simply root after standing on it for at least 3 seconds. I am aware that they added that that secondary active to his E, but it is extremely rare that singed is able to actually utilize that root.
I propose they just remove that secondary effect to his E and just have targets get rooted if they have been standing in his pool for 3 seconds. Also, another great CC would be for his W to pull enemies to center if they attempt to DASH(not blink) out of it.
