I have completed clan health and CW activity data analysis. For seasons 55 and 54 I used
https://wz-cw.5smith.ru Season 56 data has been gathered manually.
The above is overview of clan activity within CW season 56 clans. Any player who has played within last 30 days has been considered to be active. Out of 85 participating clans, 68 had activity rate above 50% and 55 had at least 70% activity rate. No significant activity differences have been spotted between capped and uncapped clans.
The above data covers Clan League 17th season clans. Yet again most of clans are healthy. Some Division A clans have merged since the end of last CL season, so it accounts for lower activity in this tier.
This is the final table on clan health subject. It depicts activity of all clans which have been open during CW Season 56. "Genuine" are independent clans. These clans are further split into capped and uncapped clan categories. "Other" refers to all secondary clans which are part of bigger clan groups. Independent clans overall tend to be much healthier than other clans.
This table shows average game amount played by TOP 25 clans over the whole duration of season 56. Percentage values show how that particular day compares to peak activity. First 4 days have been most active and final 2 days had the lowest amount of player participation.
This data by itself is nothing special. First few days can be explained by player excitement for a new season. Near the end of season it becomes clearer which clan is going to take which place in the leaderboard, so there's less reasons to keep playing at that point.
This is data of overall clan activity during season 56. "Per active" refers to total amount of players who have played withing last 30 days. "Per participant" only considers players who played in Clan Wars. The purpose of this table is to showcase that having more players in a clan does not automatically translate into higher CW participation rates.
This table showcases direct activity comparison between first and last 3/7 days of season 56. The amount of average games generally has decreased for majority of clans throughout this season. Among usual CW heavy hitters, most significant activity drops happened within After_Dark, Myth Busters, Harmony, The Last Alliance and Optimum.
This data showcases top clan daily CW activity decline in season 56. For clarity, Season 54 lasted for 23 days, season 55 for 11 days and 56th season took 21 days to finish. TOP rankings/clans are different for each season. Likely explanation on why activity shrunk the most in top 5/10 is that some of the competing clans have received lower scores due to 51+ player penalties.
This and the remaining tables showcase motivated player decline within clans. These are players who play on at least 70% of all days. It's important to state that season 55 was shorter than usual, so it might have contributed to higher amount of CW regular players during that season. Most demoralized clans were Harmony, The Last Alliance, knyte club and Myth Busters.
The final 2 tables go into more detail on motivated player decrease.
Below is for capped clans:Below is for 51+ player clans:Each season the total participating amount of capped and uncapped clans differed, so it made "all" category less accurate.
Primary reason why some positive results appear is that multiple uncapped clans had significant ranking falls due to CW scoring penalties. If less active uncapped clans don't appear in TOP X it is inevitably going to give a large boost to motivated player average.
All top categories had more small clans than usual and this also tanked motivation score. Main takeaway from this data is that now small clans can get higher rankings with less effort.
Season 56 introduced better rewards, more templates and revised scoring system. In spite of all these, there was no increase in player activity. Based on the data, it can be stated that at bare minimum CW season 56 saw a slight decrease in player motivation and total amount of played games.
Another conclusion is that there is no clan health issue as most CW clans have active communities. The real problem is the lack of player care for Clan Wars events. From all active clan players, only up to ~15% sometimes play in CW and less than 5% are regular participants. All things considered, Clan Wars are a deeply unpopular activity.
