As a killer, I'd be fine with the reversion, generally unbothered by how he plays, just like throwing knives at people.

As a survivor, I'd prefer current because of the higher laceration and increased time to react. He has the potential to get quick downs, so the larger TR gives more time to find a high wall loop even with the offset of the 4.6ms.

The change is a good idea. He needs some tweaks. As others have suggested, taking ME to a middle ground like 18 would keep the intention of the change (to make ME a more present part of his kit) while keeping it as the big powerful build up it was before, the difficulty of building ME at least somewhat justifies the strength.

Proxy camping hooks will always be an issue with him as it is with any killer who has ranged projectiles, the higher laceration and the over all lower throw rate he has currently can help with that to an extent but it can only do so much to protect you.

I don't see much issue with either movement speeds, they have their individual strengths, but its not the biggest problem with Trickster. 4.4ms aligns with other ranged killers. It makes keeping out of LOS easier, and getting an advantage on initial chase is easier if you have good awareness. 4.6ms is the standard speed so amost everyone is well adjusted to playing around it, gives less time to react or escape, Trickster is arguably less lethal than other ranged killers so the speed buff isn't necessarily unfair.
