but I'm constantly wondering about the choices they've made and I'm really struggling to understand.
You've upgraded many classes and nerfed others, changing skills that throw the balance of Oder/chaos, Melee/range, Magic/physics off balance. WB, small squad, solo. and you're still chasing this balance.
Your last oddity, I'm not talking about L'IB where I hope to hear some news, but I think the subject has already been presented, but Riposte.
You realise that despite a 70% mitigation the riposte in this duel situation does twice as much damage as the best Choppa skill....no one can find that normal.

the solution for balancing would perhaps be to start from the beginning (AoR) and start again the modification.
Keep the stealth modifications which are a very good job you've done. And don't forget to go back to 9 targets for AEs to reduce Blob fights.
