Yeah I know, but like you said it’ll never happen. I’ve never done it, nor had it done to me, nor seen it done to anyone. First of all the player has to be on their 3rd down. Secondly, it’s not gonna happen becasue if the Pred runs up behind them they’ll hear it. Only way I see it happening is if the Pred perfectly leaps behind someone who is busy interacting with something. I highly doubt it gets much use.
I prefer the idea of having a real time effect as being something that is immediately impactful to the gameplay. Like, if one of your fireteam goes down, that’s gonna slow or weaken the whole team. Which is balanced IMO. Either the whole fireteam stays with the slower player to keep firepower up, or they leave him behind and risk an easier win for the Pred. It shouldn’t be a massive speed loss, just enough that the fire team has to carry the wounded a bit and are prevented from flying across the map like they’re on PCP. This gives the Pred a bit more wiggle room in how he approaches them. If they’re slowed, then they take longer to get from A to B. If they leave one behind, well, they’re dumb and yeah they’ll be faster but they’re down a man and have less damage potential.
And the hobbling could be implemented in various ways. Lowering stamina, which might be the way to go, in addition to having less stamina to sprint across the map they’ll also lose the ability to PARRY as much. This also means less Pred rushing in the beginning of matches if they know they have a better chance after they soften the team up.
So what about that? A Max Stamina penalty with each down?
