Honestly you sound kinda angry and i'm not sure why?
Its really not dumbed down at all like your saying, fall damage already exists in the way your talking about , if you dont slide when hitting the ground you receive damage ,its not a whole chunk of damage but its fine the way it is, i was simply stating before that if you start tweaking all these things too much and can be problematic towards level design and other elements of the game beyond our understanding , i think SD knows what there doing and it had nothing to design decsions based off "dumbing things down so they dont alienate there audience."............thats a pretty harsh and ignorant statement .
To me ,if you base it on what bullet damage is the fall damage as it is makes sense.....if you want to implement changes like that then its should be an option for hardcoe mode.
Harsh? Yes. Ignorant? Definitely not.
Anyway, in Brink you can fall approximately four stories and take a very limited amount of damage. In no case have I ever been able to kill myself from a fall. (I could probably manage it but it would take more effort than it would be worth.) Why even include fall damage then? I'd have to double check it but to my knowledge the farthest you can fall is from the top of the Security Tower to the bottom of the drainage area and even a fall from that height only takes away ~50 health. So why have any fall damage in Brink if it really doesn't matter?
To make matters worse is that the Light already dominates Brink. Giving them every incentive to parkour and no penalty for taking a misstep only helps in keeping them dominant. Why should a player care if they are jumping off of a ledge or running a route where they can fall from if the worst outcome is a bruised ego?
In the end, fall damage is very minor in the overall scheme of things. In terms of frequency, however, falling occurs more often than almost any other aspect save shooting. Even if there was a slight amount of damage that would prevent a player from regenerating health it would play a huge part in balancing Brink as the players constantly running would have to avoid falling in order to gain back their health. Such a change would benefit Heavies too since they are forced to take the slower routes. Fall damage is just one aspect of why Lights are currently broken and until SD decides to balance Brink you can expect to see them continue to dominate the game.
