Thanks for the feedback!
The current mastery system is a very early working version. We're planning on reworking it completely in our next major update. We'll be digging deeper into that in the coming devlogs but you can expect:
- Fairer mastery bonuses that give a smoother early game (less focussed on RNG)
- Stronger traits for player characters
- More options in the talent tree itself to give you more access to counters for specific enemy types.
So far we've been more focussed with making the core game fun, but we're definitely at the point where we're happy enough to focus on later game challenges a bit!
