Excited for both ^^ but can understand Nik's sentiment coz the Holy Knights were ass for the longest.
At the end of the day, I couldn't care less about Sommers or Kiringham and only really care about how those two can stimulate growth for both Sanji and Zoro and the Holy Knights currently have a lot to offer from that point of view.
- Wings not only have to get past immortality but will also have to deal fatal damage to Imu by killing his knights to weaken him which is something that only Loki has ever really done and even then he doesn't know how he did it. This is a level that even Luffy is not yet at atm. In order to do this they mostly likley have to take their CoC mastery beyond simply being able to attack with it.
- Wings need to overcome whatever hax those ancient swords present.In Zoro's case it's exciting bcoz his fight also hinges on overcoming "Gram - Sword of Wrath". I mean when last has Zoro had a sword themed fight? and in Sanji's case, still have no idea what Longinus is capable off but going of it's legends it could be very interesting.
Longinus is said to make it's weilder invincible, so it's akin to a magic wand of war that gives its possessor the ability to command and conquer unopposed. So would be mad if it'd have the ability to control cause and effect or at the very least some sort of inevitabilty about it. Kinda like attacks having a 100% hit rate so even if you see it coming you cannot evade it. Would be massive fck you to CoO users in general and as such present a massive challenge to Sanji to push his CoO to the next level and maybe even demonstrate the ability to defy said "cause an effect" with the power of love or something. That said this is Oda we are talking about lol so will temper my expectations with this one
Then there's the CoC awakening angle for Sanji as well which is also pretty exciting. It isn't simply a case of getting CoC but there's a bit of conflict there as well which makes it very interesting.
