Singed's W Feels Kinda Weak Right Now + Improvement Ideas

This has been a problem for a long time now, so much so that people only start investing points into it at level 7 and leave it out completely until then.

It has an absurd 13 second Cooldown, deals no damage and only slows for about 1.5 seconds or less in most cases because people can really easily dash out of it and you mostly just hit the enemy with the tip of it. The early 35% slow at rank one is really bad aswell. It also has a cast time and for a champion like Singed who doesn't really want to stand still, this kinda sucks. The only cool thing about it is the combination with his E, but for that you actually have to walk up to the enemy, for what you would probably use his W in the first place.

If you compare it to other slowing abilities of similar champions you start to realize just how bad of a spell it is. Gragas' Q has a slow with simular values but for guaranteed 2 seconds that increases over time if you can keep them in there or push them into the barrel. It also deals a lot of damage and has 11-7 seconds CD opposed to Singed's W.

Seju's E has an even lower CD with 10-6 seconds, that is less than half the CD of Singed's slow at max rank. It also deals a decent amount of damage with a surprisingly good scaling, slows for about the same amount and strength but has a much larger range and chance to hit multiple targets.

There have been a lot of suggestions on how to make it feel like it is worth putting points into it. One idea that I really liked was giving it the grounded mechanic of Cassio's W. Both are pretty much the same ability already right now, only that Cassio has grounded and an extra DoT. It would even make sense, how are you going to jump if your feet are stuck in the glue. Lastly it would make it actually slow people because most times the enemy would just dash out of it, so you just wasted mana and stood still while casting it for pretty much nothing, like pointed out above. With the change the enemey couldn't do that anymore.

Would like to see your opinion on that:
