I just don't get the simple fact of "making things more powerful cuz OP it's got double the stuff double the punch!!!!"I just don't see how going from punch 1 to 2 crosses the threshold into "unplayable" insanity. I get your point, and yes it'd be a big change, but it would be THAT big of a change.
Balance has to still be in game, and believe it or not punch 2 bows are easier to kill with than you think.
For example, with punch 1 you have an advantage, ok. Punch 2, the strongest knockback in Vanilla MC, you can use it to PROPEL YOURSELF WITH ELYTRA INFINITELY when the Punch 1 couldn't have done anything of such a strenght, and then we have punch 3 which is used by skill-less bowspammers that can't fight.
Now, this is a suggestion about Punch 2. As I said, in Vanilla it's the strongest bow KB and it can boost you with elytra. Its kick is so powerful you can actually manage to knock somebody horizontally if the have a wall opposite to them of max 3 blocks... It's just not gonna make the game have more variety or strategy, but just increase Bow-Spamming and camping.
