Unfortunately, it's not going to teach people to git gud, they're just going to call BS and quit the game right after trying it. Matchmaking Rating is a thing for this very reason, but antagonist mode seems to be exempt from this.
The simple fix would be to stop giving antags the map information before they enter a match, because they're spam cancelling until they get Hanging By A Thread at the moment to guarantee victory.

PS4, I don't recall if the offender was a steam or PS4 user though.

Edit: I remembered I'd recorded the game, there was no PC symbol next to their name, so I assume they were also on PS4.

I really do feel for all these new players. There have been a lot of them, but the level of the antagonists they're dealing with is very high. I feel like a temporary hotfix should be put in place only allowing inexperienced Antagonists to queue for Hanging By A Thread. This would mean fewer Antagonists would appear on that map, sure, but I think that's for the best at the moment. There seems to be a large influx of new players, but they're just getting abused by these antagonists, so I don't see many above rank 0. I've been in a game with 3 level 0's and they just get grapple-spammed and flanked constantly, until they're spawn camped sometimes. I have even been an antagonist in this scenario where I spawn-camped the team as Konstantin with my bubble, they had no chance. It has stopped me from playing antagonist mode on that map though, but most people actively seek the easy wins.

I was getting one shot by Haroc and Shae a Couple of times, The defensive Stat brings nothing with getting one shotting.

That's the strength of the snipers, but they have huge blindsides and are very vulnerable to compensate for this. They are sooo easily flanked and dealt with if you know what you're doing. This is what makes them "balanced." They also require a charge time to reach this one-shot potential.

As for Hans, well, he was considered the most obnoxious antagonist before Ginebra hit the scene, but she just blows him out of the water to be frank. Hans is definitely the strongest of the launch characters, but he doesn't break the game like Ginebra does. As I've stated numerous times now, her being the fastest, tankiest character, with wall climbing and stealth makes her gross as a raider. She just runs around, or runs and hides whenever the survive countdown starts. And I brought this up primarily as a raider player, it's frustrating playing with these Ginebras on my team.

The 0.5 second inactivity on transformation is her ONE limitation, and you're asking to remove it. She's already above the other characters in most facets of her design, and even this one small weakness is easy to play around. Yet another post just went up about how crappy it is to play as an antagonist with a Ginebra against you, the people asking for the removal of her only limitation need to play a bit more against Ginebras to understand how truly overpowered she really is. She's single-handedly dragging down the game, but hey, it's nice if you main her, right?

She's a rash if you're an antagonist, but even when I find her on my team, 30% of the time I find her hiding off in a corner or inaccessible space not participating in the game. Please make her always visible in cougar mode, and nerf her damn weapon. It's crazy trying to take her down with her ridiculous movement speed, and even Hans can't counter her because his projectiles are hard to hit with under normal circumstances, and she runs circles around him. Heck, I'd even take an instant transformation if you nerfed her crossbow, maxed out her stress in cougar form, and either reduced the speed of the form, or the climbing height.

Edit: I'd just like to add, that Ginebra makes the snipers almost completely irrelevant. She has almost double the hitpoints, passive projectile damage reduction, a crazy gap widener/closer, and her weapon does obscene damage. Harec, in particular, needs a large buff to be competitive in this meta.

This seems to be a common problem. Interactable objects will sometimes bug out. I've had it on the transformers in Prologue, the orbs in A Breath of Hope, Shae's electrocution in In Shock, the protector in A Fistful of Sand... basically anything really, lol. It's frustrating when it happens, but it seems to be an engine-wide problem?

Well put, some good suggestions as well. I hope they consider these changes.
