Guild Wars 2

i have been running alot of dungeons lately to farm money for my legendary, but i noticed when i do runs in under 10 min the next run ( and another path) gives les tokens. even an whole other dungeon gives less tokens.
for exemple:

i run Cof p1 and p1 afther that i do AC p1 , p2 and p3
if i do them all within 1 hour ( can easly do that with a smooth guild party)
and i start TA afther that i only get like 45 or 30 tokens for TA….

whats up with that?!

the Balthazar event is also bugged in the Far Shiverpeaks server
