Interesting about ff frequency/numbers of AZ and Vegas. From more general feeling, there is a significant amount of remaining player base in AZ or colo and to lesser degree, fairbanks of players that have never really ventured to the newer-ish worlds or played actively (ida, juraez, kansas, vegas). There is another significant collection of players that play these later worlds who tend to pack up and head to new world when opens, then next,, leaving significant dop in player base and ff activity behind so same comparison of AZ/Vegas will look significant different in 2 months. .
Inno did good call and migrated dutch players to AZ (not as great o migrate to deadish worlds and idaho the w1 players of 14 years on 4 year world still waiting to see what means) In AZ one side was consistently strong remained long standing, other side of 3 alliances worked hard to build up and boy do they hurt in damage but did great job, the dutch players coming there benefited hat world, tho defends do tend to be easier for both sides.
Also surprising amount that spread thoughout all using different toon names (which is another factor is if inno ever combines but agree should) So in looking at asdf's data , in 2 months from now AZ numbers have loyal player base and likely wont experience big drop with opening M world. The newer-ish worlds consistently see drop each year as new opens, so can see why ask is for every 2 year opening worlds.
Colo unique as heavily inno directed, but allows the 2 groups to come together, enjoy new game friendships, and learn from each other and alot activity. AZ is 100% player directed.
One thing would like to add on wtth new levels is .. agree with above to make ff a desired choice to ff rather then chuchbuild. Has been stated for years, as other ideas as well .. but inceease oveall xp reward perhaps (6K xp for damagers if full battle is regular), but also to address the long long disparity of tanks if lucky might dodge 100000 dodgs but only get half or third of xp from ff's tho there every time. Adds up after every ff for year so tanks going to ff's may consider building church
