As time goes on, I can't help noticing that more and more content is about this kind of fake difficulty involving implausibly massive and utterly ludicrous engagements. And when you do get a nice small engagement, you're fighting a boss that uses the most incredibly cheap one-shot kills and un-counterable attacks in order to be "challenging".
Fair or big rewards. Pick 1. If it was a fair fight, the match would be over in seconds and it wouldn't be fulfilling either from a combat perspective or even rewards. You want big rewards then the AI gets to cheat. You can't have both. Although, some of the tactics that Cryptic has given to the AI borders on completely unfair.
