I for one believe as there's many different type of players, there's players willing to try out different things.
The only problem I see with the current cleanse system is the hard cap on cleanse points you can hold at a time, I see that you can only hold 3 cleanse points at a time (Sorry if I'm wrong), I believe as long as we remove the hard cap on cleanse points we should be able to solve the issue. Making players that are level 30, hold way more than the 30 cleanse points they have.
Additional to that, we could make it so, certain skills cost lest cleanse points to forget, say a skill with a base cost of 5 will take 0.5 cleanse points and a skill with a base cost of 10 will take 1 cleanse point. It will make it so testing skills will be easier while still keeping a challenge.
As important as it is to test things in the macro aspect of the game (how you progress as a whole, how it feels and how much time investment do you need to make, there's not that many players detailed and focused enough to record their experiences fully and be able to conceptualize and transmit their experiences fully), while in the micro aspect (every task and specialization) we can much simply provide opinions and ideas for each individual thing. We'll certainly fail to balance out the game as a whole this way, but we'll offer reviews and ideas for many more skills that have certainly not been tested out.
True that doing this, we'll divide players between doing things as a whole and specializing on something. But so far it's been working just fine. We have people like @Jiivita focusing on each individual piece of content, @Arkefyre on jump mechanics, @Spoygg on beacon interaction, @Boundless-tester on progression as a whole. I say we're losing something by making cleanse points easier (balance and general sense of the game as a whole) but we're gaining information on the plethora of skills we currently hold.
A different version of the game seems like a good idea, but how hard and time consuming will it truly be? Having more characters and eliminating the hard cap on cleanse points should be enough in my opinion. I trust this community to do good with it.
