Turning the Hexblade "Patron" into modular powers

[Great Dragon]

@Grod:
Whip with Green Flame Blade is also cool.

Perhaps there's merit to "start caster" as the explanation for why warlocks don't start out gishing well.

However, by that token...why is Hexblade needed as a Patron?

See, that's the thing.

I see lots of DMs either modifying the (original) Hexblade, or just flat out banning that Patron from their games.

I like what the "original" Hexblade does, but I do change it so that it doesn't become the "go to" Gish class.

After all, Gish-ing isn't supposed to be (super) easy to achieve.
