I think it would help give meaning (and therefore perhaps also desirability?) to FP if they were "on the same scale" as kills (i.e. 1 FP per kill as FDA suggested).
FP rewards for other actions would clearly then all need to be relative to that, but rather than just scale the existing values I think they could do with a rethink (e.g. flag touch/throw/cap ratios, sentry take down maybe a function of kills the sentry got since being built or something, maybe something similar for demoman take down, possibly kill assists as discussed above).
Dylstew, sorry we stole your thread!
