2d4 does:
2, 3, 4, 5
3, 4, 5, 6
4, 5, 6, 7
5, 6, 7, 8
look, it deals out
dmg 5: 25%
dmg 4 or 6: 3/16 each
dmg 3 or 7: 12.5% each
dmg 1 or 8: 1/16 each
in case of 1d8, it does dmg:
1, 2, 3, 4, 5, 6, 7, 8
with equal chance each: 12.5%
in long run, average dmg matters, and 2d4 deals out more average dmg and more chances of average dmg, so 2d4 is better
