@Cheese9Man NC is def alternative "can't understand why people thought he could just replace Gibby completely without Gibbs getting nerfed". First weakness is that he can't protect from over head unless Wattson is on the team. Won a fight and eventually the game because of this combination, match up wise the other team is forced is either waste resource to destroy a individual wall or push closer. It sounds like a cozy situation but another match showed that Rampart could easily stop this at the cost of planting her ult and her wall "You need to plant cause it will still cost alot of ammo for each wall, but planting gives a infinite supply and damage boost helps to quickly destroy em." Fuse can also achieve similar results with his tactical.
Fun facts - messing around alone in firing range shown me some bugs, not sure if it's limited to range tho. Ults that damage "Gib, Bang, Fuse, Crypto - cause it damages / destroys other set ups" has no effect on the wall itself, but tacticals do "Mag, Valk, Fuse". Mag's ult can potentially phase through a wall "needs to bounce once tho". Would like to see if somebody else can replicate these with 2 people, or if it was just my stupidity cause technically they were my castle walls the whole time.
