As an update for the mind skill sense weakness I have now taken tier 2 and tier 3 with the same viking units:
Warrior Maiden, Berzerker, Jarl, Axe thrower, Soothsayer.
Lvl 1 gives a universal +6% critical, Lvl 2 gives nothing and level 3 gave Warrior Maidens and Axe Throwers +2% critical chance and everything else +3%. I initially thought that it increased the percentage dependent on the units base crit rating but soothsayers went from 20% crit to 23% whilst axe throwers went from 24% to 26% as did Warrior Maidens.
So now I am officially confused - and have 22 mind runes to use
