For Wind Archer's Gale Barrier I think it should be based on the skill uptime instead of the %hp of the barrier itself. It would make keeping up skills less tedious(WA got like 8ish buff to keep up), and it would the class a little stronger and doesn't punish the player for getting hit a lot
Make Wonderoid and other exclusive heart generic so we can use any Androids. No point in these cool event Androids given if the heart is not perm/junk content.
