You didn't refute anything in their post, you just asked them to design 13+ sub-classes. This isn't an argument. This is barely even a response.okay in order
1 how do they differ both mechanically and thematically from other bards?
2 this one is a no brainer and should be there already.
3 how do you make it not teifling default or hell warlock is the real question.
4 a that would make the monk even more MAD as abyss also why are all monk subclasses pure fighting styles it is kinda dull but could work would need some offence abilities to not be dull playing them.
5 how would they not just overlap with the necromancer or the two undead warlocks?
6 okay the thematic could work but what does it bring to the druid not presently there?
7 would be MAD as anything also other than stat change what does it bring?
8 that would need lots of spells being made first.
9 how would that even play?
10 overlaps a lot with the new barbarian subclass also how do we deal with it being unusable by phb races?
11 we have too many magic fighter subclasses as there are at this point we need the arcane gish just so people stop cluttering up the fighter.
12 okay but mechanically what does it add also we lack sufficient plant monster for that to work right now.
13 we already have it was in swords coast adventure guide.
define setting specific that is not just a slight variation of a present subclass?
psionics needs a full class first before we really make subclasses as at present they will just end up with more quarter casters.
consider both mechanical and thematic.
