I'm still thinking of going back to creating a Warlord.
My last attempts were using the ROGUE progression as a framework, because I think it would be cool to have another class with At-Will only abilities in the core class. But I'm really interested in the Warlock's mix-and-match framework right now.
But I was also thinking about the replacement for the 2 Spells a Warlock normally get and then I remembered the Psy Dice in that one UA... What if the Warlord had a 'Gambit' die? A type of 'push your luck' mechanic?
If you want to use one of your 'gambit' techniques you have to roll the Gambit die and if you roll a certain number you can't use any until you finish a short rest? I think there's something there.
Not sure if it needs to work exactly like the old psy die or somethng else... Maybe you have a certain number of those dice and when you do you action you can add more of them but if you roll the wrong number on any of them the gambit fails and you remove the die with the bad number from your pool? Maybe the Gambit works if you roll BELOW your proficiency bonus and each gambit has a different type of dice it asks you to roll, with the easiest one using d4 but the more difficult ones use d12? Or the opposite, your gambit dice improves over time and each gambit technique has a DC you have to beat with your die so the early ones gets easier as your dice becomes bigger. Just spitballing here.
It's just something that came to me I haven't actually designed anything concrete.
I'm actually happy to hear it got significant buffs. I haven't followed the UAs that closely because I didn't have opportunities to test them out.
