gotta look at all avenues before advancing! but yeah.. i do the perma-death thing. I feel without it, it would just be too simple and no real punishment.
also... if a member has speed +5 than the opposition, it will attack twice. 5 is the number to aim for, or avoid.
edit
---okay, after a few ridiculous deaths.. i now understand casual modes appeal. Didn't think 'hard' mode would be this bad.. but then again.. half my squad is underleveled.. which is a bad move on my part, focusing only on 2-3 players to level 10 atm, rest are 3-5.. and im battling lvl 7-9
