I will start off by mentioning that all my characters are low level and I would not know if at higher levels some of the autobots tasks would become "easier" or more common but it is my experience that alot of these decept/pred tasks happen all the time compared to much less frequently for the autobo/maximals.
Some of these are small things such as all decept/preds changing the colour of their alt modes so that none are red while alot of auto/maxis might be reluctant to change their character names. And damn there are alot of Primes
The tasks that stand out to me at least, maybe others don't feel the same, as being tilted in favor of the decpts/preds are:
TASK FOUR
