Insider is a great system/tool to work out many (if not most) of the bugs before release.
And to top it off by playing in Insider for 60 minutes a week, we are rewarded with beautifull cosmetics and gold.
I myself am at week 25 right now. But some people out there have already achieved much more, up to 180+ weeks. So that means that there are over 180 rewards released already. I'm running behind on more then 160 rewards. And maybe there could be a way to use this in a way that benefits Rare (getting more data) and doesn't take away from the work others have put in.
I continue with the way things are today.
Each week I play my 60 minutes (or a little more) but not much more because progress doesn't transfer to the base game. I mostly do this on saturday morning. And many weeks, there will have only been one update to Insider that week. So I'll be testing the next version and if I find bugs, I'll report them.
But there are weeks, especially right before a release, when Rare will update Insider 2-3 times. And I can imagine that players who already reached their hour for that week, won't always be hurrying to log back in for more, before the next reward unlocks. Which means that when Rare is pushing more updates, they will get less and less data from each version.
And so to my suggestion, to how it could be.
What if instead of once every week, Rare would allow you to earn a reward once every update. While still releasing the new rewards at the same rate as they do now.
This would allow players who started insiders at a later date, to slowly catch up on the rewards. Slowly being the word because it would still take years of dedicated test-playing to catch up.
By doing this, not only do newer players benefit, but Rare will recieve a lot more data from testers. Even in those weeks where they put multiple updates out there.
And for the players who already have all rewards? Like I said, it would be best to not increase the amount of new cosmetics being released. BUT Players who already have all the other rewards might get a bigger gold and dubloon reward then the ones given out now. (cause lets be honest the 3000 gold you get most weeks wont even buy you a cannonball crate)
TLDR:
Rare will get more precious data
Newer players would be able to catch up over the course of several years
Older Insider players get special increased gold rewards for the extra participations, as a reward for supporting Insider for so many years.
