will the level 99 limit be increased in further updates? also will you add more legendary weapons? and will you add a way to disassemble specific legendary armor pieces or someway to exchange them for another legendary piece?
It's possible to increase the max level. I have no plans for it at the moment, but depending on the amount of content in the future, I might increase it later.
More legendary weapons are very likely.
It's unlikely that a way to exchange legendary items will get added to the game.
