I'm disappointed about no Oath of Liberty, but I'll take a look at what they are bringing, when they get around to getting the page to work.
First, it's barely a playtest. It's a concept test.Not good enough.
Otherwise, why have an open playtest at all? Why did they have an open playtest of 5e, and classes WOTC clearly knew people wanted? Even on concepts WOTC already "knows" people want, feedback on whether the execution of it is headed in the right direction is important?
Which is probably why we saw the arcane archer at all.Example: The recent Fighter UA. People have wanted an Arcane Archer for a while. But we'd also like to see the first drafts of how WOTC plans to execute bringing it about. As we've seen from the feedback, they're not exactly on the right track. Useful information.
So...
Death Cleric and Oathbreaker Paladin= must be evil.
Treachery Paladins and Hell Knights= no alignment restrictions?
What?
I think removing alignment restrictions was always a good idea. I ignore them for Death Clerics and Oathbreaker Paladins.
I for one don't think there is anything inherently evil in Treachery's abilities, just a double dose of sneakiness and selfishness. If I can play a Good Rogue, I can play a Good Treachery Paladin. Conquest on the other hand... I think it's hard to justify conquering and subjugating as not evil but if anyone can do it it'll be my players ;-)
