Can Tahm Kench get a Compensational buff?

This Lovable catfish has sadly not been doing very well when it comes to win-rate. Usually this would call for a buff but i know that a lot of people out there hate the guy for being very annoying. So i think the best solution would be a compensational buff.

Here is what i see is currently wrong or underpowered/overpowered in his kit:

His W, now i know that most people might disagree but hear me out: His W is both powerful and weak at the same time. When used on an enemy it is very powerful (maybe too powerful) but when you use it on an ally it becomes pretty meh.

Here is what i propose happens to it:

When eating an enemy it does (for example) 5-10% dmg based on how long you keep them in your stomach. This value would increase the more skills you put in it.

Lv1: 5-10% Lv2: 10-15% Lv3: 15-20% Lv4: 25-30% Lv:5 30-35%

For his ally side of it, instead of giving movement speed ONLY WHEN MOVING TOWARDS ENEMIES (which i have found to be useful never) it gives you movement speed regardless. The values could stay the same, the only thing that bothers me is that his W on allies is mainly used to save allies (aka run away) but the movement speed is only activated when running TOWARDS enemies making it kind of useless.

Let me know what you think of these changes!

Tahm kench mains: Would the movement speed be more useful? PPL who hate laning against him: Would this make him less frustrating to play against?

And finally, do you like the change in general?
