Meh, they simply don't need a flat buff. They need some (minor) reworking. Tone down the horde bonus in exchange for upgrading the base stats for example. Or change the shield bonus to also serve a more general purpose, say it gives re-rolls if the attack has no rend. Or take a hard look at how much value the banner and musician actually give, especially the musician now that we can teleport. Or just change how horde bonusses work in general (I like the skaven one that's just "if you have more dudes", a unit of 10 still gets the bonus in most engagements in that system). Also, I'm curious, how reliable is the optimum case? Getting all 40 in range to both bite and use their weapon seems unlikely to ever happen (unless your opponent is being mindbogglingly bad), and 2 rows of 10 spears is still only 40 spears and 20 bites under the best circumstances. In a sunclaw with re-rolls from the sunblood & the starpriest's venom that'd force, 15 saves with -1 rend from the spear and like 5 from the bites 1 or 2 of which might be double damage. That's not exectly asthonishing... Is it somehow weirdly common for horde units to get the entire horde in range or something? Cuz if it's not even the best realistic circumenstances aren't exactly overwhelming.
