As a reminder the game is still in EA and not everything is in yet, or working as it will be in the final.
For example, there is no Dodge Action in yet, but there will be at some point.
If so, great, Rogue can play like Rogue.
Apparently only a few feats were implemented, but it kinda bugs me that GWM was implemented and Sharpshooter was not, given that it is its "sister" feat. Due to TWF being severely underpowered in 5E compared to previous editions, you kinda have an incentive to go for ranged combat with DEX based characters. So I hope they are not cutting SS and it is only an EA thing.
I don't think feats are implemented at this point because they don't have all, or even enough of them ready.
Alingment are not just concepts on D&D universe. Order VS Chaos and Good VS Evil are FORCES in constant conflict. A campaign in mid of a war among devils and demons is far more a chaos vs order than good vs evil,. A LG paladin struggling to chose between "law" or "good" when he is on a L.E. town...
Back on 2e, clerics and paladins could even lose his powers if they step away from their deity's alignment.
Celestials and Fiends and such still exist. Clerics and Paladins losing their powers if they displease their deity still exists.
In the Players’ Handbook. You’re told to pick an alignment for your character. And all of the alignments are defined and explained. All the gods are giving alignments, the Paladin is text book lawful good, certain sentient weapons wont cooperate with opposed alignments, the arguments that its not in there is a fallacy. If you choose not to great but its in there. Unfortunately wotc is moving towards the everyone is nice and special with drow no longer being evil, wouldn't be surprised if red dragons turn into cuddle bunnies
This is a strawman, and not even a very good one.
Humans can be of any alignment in D&D, and yet, amazingly, the game still allows for the possibility of human antagonists to the player characters. Removing the label of "Usually Evil" from a creature type does not mean that they cannot be an antagonist or enemy to the player characters.
