The Warlock is a weird class thats kinda all over the place and has some glaring design inconsistencies. I woulds not be overtly surprised that when 6th Edition rolls around in 2 years he will be one of the classes that has had the most work put into it.
One thing that has always weirded me out was how your Warlock Patron has no impact on the Pact Boon you take. I hope they change that in the future.
