Anyway, if I'm reading the rules correctly Die Hard with the current death save rules seems really game-warping. 1 rank in it (75 exp) takes you from a 20% chance of dying on any given death save to a 4% chance (!) and from a 20% chance of stabilizing to a 36% chance.
2 ranks in it (225 EXP, this is admittedly pretty expensive) takes you from a 20% chance of dying to a .8% (!!!) chance, and from a 20% chance of stabilizing to a 48.8% chance.
It seems to me like having this massive difference in character survivability between people who take Die Hard and people who don't might not be very healthy for the game. Especially if it's supposed to be a killy type of game, having a talent which pretty much eliminates the possibility of death (except to overkill or non-combat stuff) in this way might not be the best.
Therefore, I took it twice when I was reallocating EXP and will be abusing it until it gets fixed.
