and when we calculate the buffs like rampage or rip gore and tear? having in the case of the leader 9 2h vs 15 dual attacks when 16,... percent of the hits are crits, it seems a bit different as we have more quality 2h hits landing compared to withouth rampage.
in terms of the archers, i think the arrowboyzs option represents their ability to shoot and then still close in while the ungors ability isnt dice-dependent and gives flat +1 / +2 shots in that turn. ungors only point is to shoot, arrowboyz can charge with their hp in melee too and are more expensive while beasts of chaos have for this job ways bigger guys compared to the used mass of nearly all the same mediocre bulky bonesplitterz if we compare the statlines and extreme scales of the 2 armies. nonetheless are both armies basically jack of all trades armies as they are rather fast, enduring and hart hitting at once.
