This is like a one time feedback to Ubi directly, i won't be responding back.

Warden: Needs more moves, became too predictable and everyone and their mother knows what to expect from a Warden at this point, which is why fighting agaisn't him is easier generally across all players.

Bringing him up to the same move count as other Vanguards is a good idea.
Or if you think you will go bankrupt if you introduce some new moves, just throw in crushing counter from all sides. but balance the damage accordingly.
I think even my mother knows to not attack a Warden from top at this point.

Lawbringer: i fully disagree with speed increase changes with this character in the new testing grounds. you already speed him up in the rework and its okay now, no need to speed him up even more, its starting to look very uncomfortable. and outside the fantesy of this character.

What i do suggest is reducing the toplight speed equal to speed of his side lights, but it is an augmented top light just like the side lights. therefore making them all parryable and reactable, more so then an assassin, as it should be.

But one really important thing, for the love of god make his flip move how it was before, not interruptible. or give some sort of hyper armor that kicks in after some time.

Let me make my case please, so with this sweeping change that all unique moves are now interruptible, Lawbringer took the most hit from this compared to someone like Shugoki, if Shugoki lands his demons embrace, he deals damage, and heals while applying this move. and after throwing the enemy down has a "chance" for extra damage if enemy isn't paying attention.

Lawbringers flip its harder to land and hardly even rewards you for pulling it off. if you're trying to make it so in those 4v4 teamplays where allies help its worth it, don't. because most people play the game solo. and iv'e gotten interrupted almost every... single... time after pulling the move off, by my ally. and even in 1v1 situations its still harder and not rewarding as Demons Embrace. don't nerft Shugoki, buff this move of the Lawbringer.

Conqueror: Just wanted to tell how i feel like, sides the bash repeat this boy has no real opener, but if that's how this character is then so be it, its just that i feel pretty bad that you nerfed his damages, he was pretty okay as he was, given how he survived the constant barrage of nerfs you gave this hero. that was "back then" well deserved. but now it feels like you just hate Conqueror because... idk... it was OP back then. top heavy opener to 14 damage feels underwhelming.

I pretty much exclusively play these 3 Heros. Warden being one i started with. Lawbringer second, Conqueror the third, though all 3 of them i played just as much since early marching fire.

Overall opinion about testing grounds, I feel like as you wanted to make For Honor more aggressive, you missed the mark in this upcoming patch.speeding things up and outright removing stamina punishes no longer feels like you're encouraging players to be aggressive in a unique way. it just feels like you're rewarding foolish play. less parries. less blocks. more attacks.

I know that this was your intention to an extend, and i'll tell you that i feel that the current live patch struck that balance pretty well. while the new patch feels like you aren't trying to strike a balance between fast and slow because you learned from your mistakes when the game was too slow and clunky. it just feels like you're flipping the table entirely and making the game too fast.
