Noticing that this was starting to get more attention and people saying certain units are really good (or maybe even not so good) I wanted to make this so if you think something is too good, or not good enough let me know and I will test it out and post my results. If after you are getting different results let me know exactly how you used them, what you did differently etc.

In tests I will do units 1v1 (I've gotten quite good at getting the general to fight off to the side and not killing theirs or mine) which while it is not the be all end all test as some units do perform better under certain functions (which I will change the tests if needed to try and take into account) will at least give some idea of the strength.

I saw Grave Guards mentioned as a unit that was too good, so ran it through some fights with the following results:

vs Spearmen: Win end 62 GG vs 22 Spear.
vs Spearmen (Shields): Win end 76 GG 56 Spear Shields
vs Swordsmen: Draw end 54 GG 54 Swords
Vs Gsword: Lose end 0 GG 60 Gswords
Vs Halbards: Lose end 0 GG 71 Halbards
Vs Miners: Lose end 0 GG 80 Miners

If anyone thinks I should go vs more units (orcs/chaos) let me know and I will but from the above it seems they lose to most other tier 2 infantry (halbard/gswords, miners are tier 1 and if miners beat them I doubt any other dwarf unit would lose) in general so they don't seem too good to me.
