Cassiopeia's W can cover more areacassiopeia is allowed to ground but singed can't?

Covers more area,dealing DAMAGE,Slowing for more,got the same range,lasts about the same,got the same base cooldown at max rank,and the most important,GROUNDS targets, Compared to Miasma,Mega Adhesive is just a shitty version of this ability,just lackluster. The only difference is that it is insta created, have a minimum range and "roots" if someone's is flange into it(happenes 1 per match usually) Also it should get a cast visual animation,currently singed orgasms for 0.25 seconds and a magical pool of random sht spawns from another dimension
