Couple of remarks:
- arcane bolt - in description has %d of damage
- sweep and whirlpool - at certain turn it has appeared suddenly a long pause (around 10 sec) after animation and before a damage is calculated. Recently i have re-installed game completely (just upgraded to win8), and the error remains. If I, however, start a game from scratch then it works normally.
- I am around turn 200 and the lag is really, really ugly, and I got a good pc. It also crushes every second load or so, and at the end of every 4-5 turn (i am playing version .7 if i remember correctly)
- i got sov from surrounding and she has deadly poisonous strike and improved poisonous strike - those skills lack description (meleeappliesspell shows up)
Regarding balance:
I am not sure how the calculation of damage is done, i presume that it is calculated for each soldier in unit separately (that's why when 7 archers shoot at you, you almost never get dodge, even if unit is dodge maxed). If this is a case, backswing should always trigger whenever even a single soldier misses. That is, if i have 4 infantry unit troop, and two of them miss, this two should back-swing. That would make big axes more useful. I still find spears, due to two bonus, the most useful - dodge is not very effective so against archers even shields do not help much (only speed does).
Heroes: Melee heroes rule. I have lord Verga, right now on lvl 9 and he alone annihilates deadly armies, dragons etc. Since lvl 6 he is extremely powerful. On the other hand, i have one 7 lvl mage and 6 lvl archer and they clearly suck, especially archer.
Lord Verga also has right now 81 attack, including only 13 from weapon. Such a high attack makes the choice of weapon secondary issue, it does not really matter if he fights with a dagger or huge axe (81 or 86 attack correspondingly), hence weapon that provides additional counter attack and initiative bonus is the best. Also having a shield is very good bonus. It somehow does not seem right. I think that either weapons or skills (warrior etc.) instead of having +x attack bonus should have +x% accumulative one. For instance, axe would double your damage, and dagger would give you 80% (plus additional, let's say +3 attack). I know that it would probably involve huge change in mechanic, but to see my deadliest one-man slaughter machine running around with tiny dagger and taking on tons of enemy looks silly.
