Sabo changes. I gave them some thought and... NO.
I didn't want to rush to conclusions, so I took some time, played a little more as killer and surv, and even if it's a little situational, it's too strong. Here are some thoughts.
-It's the same as the old sabo, but now you don't need to pre-sabo at 99%, so it's a buff. I know that you can sabo less hooks, but still you can spend time on gens while waiting for the sabo play.
-Killer's time is gold, even more now that old ruin is "gone", so missing 1 hook can make you lose the match, mainly at the beginning of the match, so one sabo can unbalance the match and there's not much you can do about it.
-It doesn't require skill or timing, like a FL save or a pallet save, you just have to guess correctly that the killer is going to the hook you're waiting and that's it, a free escape.
-With flashlights you could look at a wall, but if you're half way to a hook and you realize they're gonna sabo, that's it, you have no time to go to another hook, you lost all the time it took you to hit the survivor twice and you have to start all over with a new survivor. Meanwhile, the other survivors keep working on gens. It kills momentum like the old DS.
-You can't even try to down the survivor saboing, since it's faster than the hit cooldown, so if you interrupt a healthy survivor saboing, you hit him, and he has time to break the hook and even escape your second hit, and by that time, the survivor you're carrying goes free. Almost 0 risk for survivors and easier to pull than a flashlight or pallet save.
-Hangman's trick's changes apparently are not going live, so it's not balanced because there is a perk that can counter it. Also I shouldn't be forced to use use a perk slot just because sabo is now a thing.
-If the guy is wiggling at 80-90% when you see a guy saboing, that's it, he goes free, you can't even drop him to the ground (unable to pick him back up) that way MAYBE it would be more fair, since you'll chase the sabo survivor while other survivors have to come and pick the other guy up. But no, it's all win-win for survivors.
-Killers have no way to take advantage of a mistake. For instance, a long time ago I used to run lightborn, and on purpose I picked up survivors in the open, so a flashlight guy would appear and I'd give him a free hit, sometimes even a down. Hell, even now some survivor still try to flashlight me while I'm carrying a survivor and I get free hits and downs (red ranks are a mess right now). It's a little risky for survivors. But with a sabo, at most you can give a free hit to the sabo guy and they both escape. You can't capitalize on it in anyway since they can't "miss" a sabo play.
Well, there are my two cents about the issue, hope it helps. Feel free to comment more in favor or against the sabo changes.
