I know the avenger line and the faust, the idea of the sealed sword/antigua thing is that they keep their effects and not change to completely different weapons.

The sealed sword isn't going to change. It's supposed to be a weapon with its power sealed (hence the name) and when it gets unsealed its charge becomes really powerful. That's Nick's original idea for it.
The antigua is a bit of a wierd weapon though. It could be changed to a normal damage weapon, but that might affect its use in T2 PvP.

Troika means three, but what do the other names mean... ?

They're names for Yugoslavian/Scandinavian/Russian mountains or something like that.

I didn't want to remove the Magnus piercing gun, the callahan will be elementar and the new 5* magnus will basically be like the old callahan.

Here's a better idea for a Magnus upgrade, from mid 40k.

Breaker lines... are player traps

Not so much, they're useful in tier 2 PvP, and they also have the highest Tier 2 status resistance in the game. They're good as an experimental armor for new players. I could also argue for their usefulness as Last Stand armors, but that's a whole 'nother story.

Cautery Sword needs a complete overhaul, but you haven't provided any information on how you plan on doing it.

my turn.
ok on adding more weapons, but:
1
Sealed Sword(the 5* could have all status effects and the aura should change to the next effect that will happen on the next charge, only normal damage)

is OP. pretty much, now it's good because it's little. if you were to expland the area it would become too much.
2 deconstructor with elemental damage= nitrome with spcialized damage =more spammers around. no, ty.

3
Brandish(a normal brandish wich deals normal damage, the color of the explosions should change every time and use the player eye colors)

a)we don't need other brandishes
b) nobody would care until normal damage beats the neutral damage, and then that one would become OP.

3
Troika(there was a 3rd troika, so why not create a complete line with a fire and a shock troika ?)

there is a third troika, cherub has it. should. well, it's a GM weapon, and I think it's on "dream on" mode. fire troika would be OP cause knockback. oh, on troika weapon lines: stun line are ballrooms, freeze lines are mountains.

4 4* and 5* breaker lines
you would like armors worse than the ones we have right now?

5 Cautery Sword upgrade ?(i know the sword was made to help players to defeat the Royal Jelly, but wouldn't it be good if this "player trap" was changed into something useful ?)

player trap? only guy selling recipies is the cobalt guy in HoH, and nobody's buying it anyway.

6
You do know about the BH, AP, DA, and GF, right?

Blackhawk? you mean Sentenza.

7
I got the Deconstructor idea from an other topic wich is rather old and i didn't want to necro(wich is the reason why most ideas aren't original). I thought about spilt normal and Elemental damage.

that's worse than before. with chaos it's more OP than a deconstructior with just elemental damage.

8
Maybe it could be changed into a "normal" brandish, but i'm not sure about this since royal jelly is already hard enough

you have problems. either lower the difficulty or get a 4-5* weapon.

you mentioned AP, GF, DA. a 4* with 3 5*? does not seem fitting.

Every single idea here has been suggested before, and you didn't add anything new to any of them. Why should I try to discuss anything on your thread, when there are dozens of more focused, better-explained threads I could necro?

And Kloriff, go see what the devs have been doing the past 7+ months. And maybe think about what you're saying before you start throwing around words you obviously don't understand.
