You know there is a difference between assumptions and facts right ??????
OK Fact....................this Nerf will make it harder for Junior players who only fight to low Attrition no conjecture no debate about this its a unfortunate Fact.
Second Fact weak Guild will still be weak Guilds but they will as stated previously be unable to get a team together and break out due to the lack of support to extend there fights. 10 or 12 active players within a 24hr period aren't going to get to get beyond the starting blocks before they're out of attrition again a unfortunate fact do the maths.
Third Fact the big Guilds won't be able to carry Junior or part time players as they do now so you'll find these guys offloaded for more senior active fighters ending up with a few "Super Guilds" which will make the odds even more unbalanced and Junior players nowhere to grow and be nurtured as is the case now.
Forth Fact look at the activity within your own Guild unless your all farmers who don't fight (if so why are you antagonising people here?), be it 1.9 threads swap threads activity dies off between GBG rounds because there isn't the influx of rewards to drive city development. Hardly healthy or conducive to the rapid growth of Junior Guild members.
I could continue but can't be bothered I'll sit back, go back to my usual server and make a decision if this nerf goes live regards deleting my city. In the mean time I'll continue Auto fighting to 120Att or thereabouts and then call it a day as I do now.
