the biggest trick is balancing the scoring system so that every class is as useful as every other class. as i see it right now the ideal team would be 6 pockets, since they are likely to topfrag and damage every game, as well as have the highest FA/D. Some things to bring into account might be frags/damage, heals taken, and medic assists.
GetawhaleI'm curious to hear what your thoughts are on the whole "people who play longer get higher stats" thing. Because I know it can become an issue based on how the scoring ends up being done. A brief experiment with fantasy stats was tried in UGC and this is what was found.. whoever played the longest games got the best stats.
obviously everything will have to be done as a ratio (frags per death, damage per minute)
