when they go berserk and if they're not engadged in melee, they will stand there and throw the javs and that really sucks. since their javs do 20% less damage, and they dont throw it as fast as the skirmshers. and then after like 10seconds or so, they get out of bloodlust if theres no units nearby, and thats a big waste of a unit and 700 denari(most other german units have 2x more men and costing only 1/2 as much.)
