Can we do something for Tahm Kench the River Boi?

(skips kiss ass part where i explain that discussion is for discussion and grammar isnt always the best)

Firstly can we move Tahms on hit damage back to his ult with the values it had before? No one asked for a stronger early game at the expense of his overall strength and seeing that he cant even get in range to use that 'stronger early game.' Next with the addition of pyke who takes Tahm Kenches mechanic and does it far better can Tahm Kench have a better working Grey health. Can his Hp5 and heals he recieves not Use up his Grey health as if that damage was never taken off until the grey health Passive / shield is used. Im not advocating that he keeps grey health when at full health let it Heal/ decay at the same amount as if he is using it for the heal but let it not be tied to his maximum health. (I hope pike gets this buff too even if i think that his healing needs to be reduced because having better healing than a tank for the same mechanic is stupid especially when he can get it to activate easier while Tahm has to afk out of a fight to get that health back. riot is stupid having all the mechanics that require you to not take damage tied to tank kits whos job it is to take damage.)
Lastly Tahm needs a useable ult I dont care if its misrable for pros he needs to either have his Cast time severely reduced when diving (without sneak adding the time back on when he opens his mouth or travel time like riot does sometimes) or have his ult not get canceled by taking damage.
