I am really tired from typing one handed, so I will keep this short:
As I said in my introductory thread for game improvement suggestions, I find the Offense tree severely lacking and underpowered. In particular, most of tier 1 choices are either too underpowered or too situational: Other than the infelicitously named Fast Adaption and Sundering Strikes, there isn’t much that is universally good. This tree needs a lot of work.
