Alright I‘ve tumbled through all of the warscrolls.
Without counting in Battalions and Allegiance Abilities no Warscroll looks really strong apart from the gaunt summoner.
I am a bit confused especially about the weapon damag values : The best weapon overall always seems to be the ensorcelled weapon with 3+,3+,-1,1 all the other weapon options lose too many attacks, hit too badly and or are conditional. Every 2+ dmg weapon loses at least one rend (most are rend zero) - surprising especially since it seems fine for Orcs to be 2+,2+,-1, +1 damage for entire hordes...
So far the Warscrolls are a bit too tame and the new Krakadrak Chaos Lord made me go „Meh?“, Knights and Varanguard made me go „meh“ very hard...I expected more reliable punch.
However there were some nice changes to the Slaughterbrute, the Mutslith changebeast and marauders. I haven‘t had a look at the chariots since I am personally not interested in them.
the whole army has several ways to grant +1 to wound, hit, +1–3 to charges and Rerolls to armour saves and all hits and wounds, yet it lacks in damage and rend.
it has mortal wound shrugs of 5+ on most units.
summarized weaknesses according ONLY to the warscrolls: A lack of High damage attacks (2+ Dmg) weakness to rend, almost no access to good rend (2+). No Warscroll feels really strong. Too many units can grant similar buffs which makes some abilities redundant (a lot of +1 to hit and wound and rerolls).
summarized strengths: A high volume of attacks with substantial buffs to hit and wound. (+1 mostly but most stats are 3+, 3+ anyway), high armor, mortal wound resistance.
Sidenote: The Warcry warbands haven‘t changed afaik
I am now very interested in what additional rules the Allegiance Abilities will add!
