On any progression-based game, we always run into the issue where giving too many class features prevents us from combining them. For example, if an upgrade grants 20% more max HP, then another allows for auto-reload, then we need 3 classes to include all cases (case 1 is buying upgrade 1, case 2 is upgrade 2 and case 3 is both), and its exponential for more upgrades preventing us from adding good variety.
I feel with Verse it would incredibly liberating in terms of design to allow us to set those player features through code via player instigation, and ideally check their setting too.
It would open up large scale progression in a massive way.
