Every single shift stone promotes some kind of bad habit Surge promotes disk follow up, Guard promotes not dodging, Vigor promotes disk spam, Adamant promotes not not hitting yourself, Stubborn promotes not realizing your taking damage, Charge promotes not learning proper combos, Volatile promotes explo cube spam, And flow promotes not learning better positioning New players are suffering from having these because they rely on their effects to avoid learning harder topics and completely stunting their improvement. There is already a shift stone tab, and a system to bp lock things, so not much would even need to be done to make this possible Personally i think locking them all to 1k bp makes the most sense, thats plenty of time to master the fundamentals without accidentally crutching on stones. Idealy you make some amount of progression to them. At 1k you get to chose 2 stones, but after you chose 2 all of the other stones require 100 more bp, afterwords each time you unlock a stone every other stone would go up in bp requirement by 100. This prevents the player from being overwhelmed by the options, and encourages them to make informed decisions on what to unlock. Overall i think making stones have to be unlocked in general, regardless of how it is done, would be very good for the health of the newer player base, as long as the unlocking process is moved a decent distance after reaching black belt Edit : Maybe 1k is much but i want to preface that im NOT saying that it HAS to be done the way im saying it could be. I dont want to just suggest "Bp lock the stones" without giving an in depth explanation as to why, and giving my thoughts on how i would go about it. The main points to this post are to bp lock the stones, and have them past black belt
