for fighting max xp is 3000 which can be doubled by catalyzer to 6000. Harvest is the same, except it is very improbable to get over 5000 xp total, i have dug over 20 suprere mats that were 25 levels above my level and still only got 5900! Craft is not limited by the action, but rather the number of mats used. I have gotten over 10,000 (with catz) for making HQ amps and HQ HA especially when overcrafting!
