I think there should be such thing as commander armor like wolver, skelly, gunslinger, cobalt commander etc. And the only way to get it is to be a vanguard and beat the final mission.
Mainly it would be harder then a danger mission cause it would be 5 star and stronger then a regular 5 star armor and you would need 4 people.
Same goes with sword bomb guns and shields.
Well i wouldn't come up with the design i would leave that to Sega/ three OOO like they did with cobalt wolver skelly etc.
Cause It is they`re game.
And also if it is stronger it would be harder to get you would need to be vanguard and finish the final mission. it would be harder then a tier 3 danger mission when you have 5 star equipment.
The game should stay balanced. More so since we have pvp.
No armor should be directly better than another just becasue it's harder to obtain.
Take at look at Shadow Lair gear... Almirian Crusader is not that great.
In that sense, shadow lairs are hard mission that should be done with 4 people after being a vanguard. Wich means your idea is a copy of something we already have in the game :P
Hmm... i completely forgot about shadow lair cause i never hear about it anymore.
and most people don't go the shadow lair because its so laggy.
Any item that's more powerful than another, even subjectively, is not going to be taken well.
Though I'll be slightly more receptive if you make it cool-looking enough.
