Sound all issues you think are there, as detailed and structured as possible, don't just say 'there are issues'. Preferably also make suggestions on how you think they should be fixed.these are almost peripheral issues to the reasons for why a unit doesn't make a certain tier or some units being where they shouldn't be at all.
We were going back and forth for three pages just to get to the poing where Rogue suggests smth that actually proves to be useful without any apparent drawbacks. And i don't want another 5 pages worth of discussion for every single issue. You see the issue ? Describe it and suggest a some way to fix it.
