I've read this thread and the one on beta. Normally, I can follow the math, but today it's all geek to me. So, I'm going to quote what Dony who truly is the King of Bugs, wrote to explain what it all means.
"This nerf, bug fix, rebalance, overhaul, call it however you want, will affect mainly average players in first 8 provinces without buffs (aws,buildings,phoenix) because counter units will live longer and do more damage to your units
And second group is high end players where killing counter units will takes them more then double amount of hits compared to before (which will lead to enemy counter units reaching your units and doing damage whereas before they died before doing that)
Obviously huge nerf for manual combat where it will take much more time to finish encounters"
Definition: Counter units are those that are buffed against you.
NOTE: This is not the bug that was 'fixed', but it might be a consequence of the fix. I get confused at this point on bug, bug fix, fixed bug, whatever. Although it's been like this since the latter part of the steel tourney, steel and planks are easier than crystal (even in the new format), so you may not have noticed the affect until this week. …and next week is scrolls.
