So i finally got my Guilty Longinus today so im gonna give my honest thoughts.
Longinus Core - Very nice core. it's very heavy so i'm very ecstatic to try this out in combos and it has good teeth which is good, definitely didn't want this core to be like Valkyrie in terms of its teeth especially with the use of a Metal Driver in its stock.
Guilty Blade - Honestly, this is probably one of the best Blades so far, it has incredible attack and it is very heavy too. Definitely gonna see use in competitive play.
2 Armor - We've seen this armor before so there isnt much to say about it, It isnt bad but it isnt the best imo. It does have good synergy with Guilty so that is a +
Karma Disk - from what i've seen so far, it actually doesnt do too bad but i'll have to do more testing on that part.
Metal Destroy - Not much to say here. It's literally just Destroy but with a metal cap, it performs the same as its previous iterations.
L-Gear - Probably one of the main reasons you should buy this. For a piece that locks Belial in High Mode, it is very powerful as it really does increase Belials attack power by quite a bit. So far, im running Dynamite Belial.Nx.Ds' (LFS) and it does pretty well. Honestly i'd say this is probably the best gear so far.
Overall - 10/10: Has nice parts, Guilty and Longinus are gonna be useful competitive and L-Gear really improves Dynamites attack power.
