Can anyone tell me how much health each of the pro classes starts with by default, and how much damage a sword assassin front grapple does?
Check out HostileBalance.ini somewhere in the game's install folder. The answers you seek lie within One thing to note, I believe that file says 150 for the sword front grapple damage, but that damage occurs 3 times for a total of 450. I don't remember all the pro healths, but I believe Assassin and Sniper have 300 base, plus 100/200/300 for bronze/silver/gold armor endorsements.
Go check the balance file (you can open with notepad) But in short: Sniper - 300 health Assassin - 300 health Assault - 500 health Support - 400 health + 200 from passive. Gunner - 700 health Tank - 700 health + 300 from passive lvl 2. Assassin's front grapple with the knife does 400, back grapple does 700. With the sword it's 150 x 3 = 450 from the front, and 1000 from behind. Armor endorsements give +100 health if bronze, +200 health if Silver, and +300 health if gold. All the extra information you might want is in the aforementioned balance file. Cheers.
