Would it really be crazy for them to mix in some of the core hexblade features like Hex Warrior into Pact of the Blade?
Wizards of the Coast is releasing an updated version of the Player's Handbook in 2024.
In their most recent playtest the Pact of the Blade Warlock was overhauled.
Many of the features of Hexblade were rolled right in to pact of the blade.
Much like the special weapon attacks that were introduced in EA, the changes to Pact of the Blade are likely based off Wizard's of the Coast playtest material.
