That's not entirely true; we stated to the devs that it's too 'easy' (for some with good toons with great gear and lots of past lives) and they created the champion feature as a response to that feedback. This didn't just happen out of the blue because the Devs did a test drive and said 'wait a minute'.
The problem with champions is that it's a terrible instrument to balance player power. Most of the time good players with good gear will blow through content without much issue, but then there are certain times when the dice beats you over the head with a room full of champion zombies and tiny spiders. And you feel like....really?
And it's worse in low end content; that's your ramp up period where you slowly get familiar with features, add feats to use tactics etc. In those champions are just stupid roadblocks and not really good challenges. To me champions should be epic encounters. Something to look forward too and something that is rewarding.
Combating a room of shadow champion rats is just off turning. It removes all form of immersion since you know those are the most powerful in the room, not the red named boss. For me at least the whole champion random debacle misses the greater point of making pivotal encounters more interesting. Like mini bosses that's worth the option. Like red named. Those are the ones Turbine should beef up. Not the shambling zombie that just spawned. It gets corny real quick in that case.
