Your math is wrong for a beastlord. It averages more hits now than it used to. 6 attacks with the new warscroll will average 5 hits, whereas the current warscroll averages 4.67 hits.
Only downgrade is vs heroes, losing reroll to wound.
Bigger buff for beastlords in brass despoilers, obviously, where it has both exploding hits and reroll 1s.
Run and charge is a relevant buff, as is making grisly trophies a non-command ability.
