Some claim this fight were easy, not realising that they are probably using a lot of overpowered mechanics. Also you should acknowledge that the current maximum difficulty is "normal", there will probably be something like a tactician mode as well.
Overpowered mechanics:
Leadership 4+: Gives you an insane amount of initiative, basically guaranteeing that your party goes first, which is probably more of a flaw with the current initiative system.
Rage+Blood Sacrifice+Warlord: All those skills are overpowered, make you deal way too much damage and allow you to chain kill all the weaker enemies.
Rage+Blood Sacrifice+Sneak+Guerilla+Snipe: Too many combined damage bonuses make oneshots too easy.
Hail Storm: Way too much damage, huge aoe and freezes. The damage is so high, that you often freeze targets that started with full magic armor.
Winter Blast: Costs 1AP, 2 turn CD and freezes for 2 rounds in an aoe.
Perma CC in electrified surfaces (or perma CC in general): Abusing the currently flawed armor+CC system which guarantees CC to work after removing a little bit of armor, allowing you to completely negate problematic foes, like the Bishop.
The list goes on, but you probably get my point by now.
Take away all those mechanics, approach this fight head on without cheesing and imagine being in tactician mode. Now tell me how fair the fight is.
