God, the whole situation with Weevil was so shit. So, you introduce a character who is "supposedly" as strong as a young Whitebeard, but never actually show or hint at what his powers are, not show him for like years, in real life, then have him beaten offscreen, which doesn't even do anything for Aramaki, as we didn't have a glimpse of the actual fight.
He may have well kept Moria as a Warlord instead of having such a non-entity introduced.
