1) Please point out where a warrior can heal, because I have played the class in game, and the only way (which does a sucky heal because he doesn't have correct stats) is to use a healing scroll in regards to a non-ability heal like pots. Your classification of jump, although you probably believe is hilarious is really kind of childish.
Of course it is childish. It is my feedback about the way D&D5 rules are implemented so far. I find it gives a very childish tone to the game.
For healing : scroll or throw one of your 100 healing potions on a friend.
