What's the standard dmg when a player without boots or anything on falls on someone?
I recall falling on a solly as a medic and there was this weird ass kill icon i'd never seen before.
I didn't think landing on someone actually dmged them.
It doesn't normally. Some severs (like the waiting room) use a gomba stomp mod that makes landing on people deal damage. In that case, you can set it however you like. There are two variables; one for percentage of current health and the other for a set amount of damage. So I could set it, for example to 25% of the target's current health + 50 damage.
The Mantreads just deal 3x whatever your fall damage would have been and you take no fall damage. Let's do some math!
A vertical rocket jump goes a maximum of 576 hammer units up.
Player hulls are 83 hammer units high.
576 - 83 = 493 hammer units worth of fall damage if you land on someone.
It seems fall damage is based on the classes' max HP and also has a random element. Average of 493 hammer units should be around 48 damage or so. Which means a mantreads hit would cause around 144 damage on average if you rocket jump for max height. Keep in mind you can also couch to add a bit of extra damage, since you'll add about 20 units to your fall distance.
I'm not sure how, exactly, gravity effects fall damage. Assuming double gravity means double distance than at 493 you'd be taking 58 fall damage for a 174 damage stomp. Actually, there's surprisingly little data on the fall damage formula. I'm tempted to do some tests to figure it out.
