You are not correct. As INNO say stated, repeatedly, the nerf will fix the problem with zero attrition. This is fact, not fantasy. Will it limit personal rewards? For some, most definitely. For others, it is unclear because only INNO has this data and they have not released it to the players. The information supplied by the few players on this forum that bothered to share it is inconclusive. At the end of the day, the nerf's impact on player rewards matters only if INNO thinks that it matters.
You are correct. It does only compromise p-low attrition. Since both are made impossible with this change. It also has very little, if any, impact on the small guilds. At least at the live servers.
In the following leagues it will have little to no impact. As SC are either rare or non existence:
Bronze
Silver
Gold (light to medium)
Gold heavy is only slightly impacted. As SC tend to be build in some seasons but are few in numbers. Most guilds relay on numbers and strengths of members, group coordination and estimating what the rivals are up to and anticipating on it. While barely relaying on SC. Last season in gold heavy, for example 2 out of 7 guilds used a few SC. The other guilds didn’t.
From platina light onwards it starts to slightly to moderately impact guilds. Since only in platina light, medium to heavy usage of SC and radiance on them appear. Some seasons in platina light are up to half of the guilds using SC. Though it’s not a full reliance.
The hardest hit by this improvement are those that relay heavily on SC. Particularly the 0-low attrition.
Further more, don’t worry though,
@jovada and a few others have tried to explain the other side of this improvement many times. It’s simple wasted time and energy cause it’s an echo chamber. The only “
correct” opinion and use of GbF is: be in a 1kD guild, overwhelm rivals, beaching them, cashing out as many rewards and battles as possible by using SC as is and repeat every season. This improvement compromises this “
correct” way of playing and thus is bad. Any other opinion, observation or on any other way of disagreement of this “
correct” way, is equally bad, if not worse, as change, judged as false or in another way rejected. Arguing in a echo chamber against the strain is like playing chess with a pigeon; no matter how good you are, the bird will fly up and flatter on the board like it won anyways.
Nothing will be forwarded out of this topic anyways. Cause it’s rightfully observed and concluded for what it is: echo chamber. A repeating discussion with the same conclusion: confirmation bias. Inno does the right thing by muting this echo chamber for themselves and looking into unbiased data collected from the servers instead.
