I think that the ETC people are still getting their act together as far as these rules go. They essentially just threw blanket limitations at all of the "problem" units (like HPA, Hydra, STank, etc.) and mechanics (cheapness of extra PD in 7th ed books given 8th ed magic rules, steadfast, etc.) of 8th without addressing more complex issues of overpowered synergies that remain viable under these rules.

The 7th edition ETC rules were 50 miles long but at least served a purpose of attempting to create a more balanced environment. That said they were pretty much a different game in the end...

I think ATM these rules largely substitute one flavor of cheese for another...not that cheese is a bad thing I personally prefer manchego and sharp cheddar.
