That's the point I don't think they need a point reduction! they can cost even less than now, but still I think they are less efficient hard hitters than many other, even bestigors are better in that role. I think GW can even bring them to 200pts if they make them good at what they are supposed to be!
I don't like usually to compare different units from different armies, but it still is a sort of a becnhmark. 7A at 4+/3+ rend -2 damage 3 + bloodgreed IS TERRIBLE no matter how you judge it:
7A at 4+ is 3,5
3,5 that wounds on 3s is 2,31 + 1/6th chance of triggering Bloodgreed which is 0,58 (that hits on 4+ and wounds on 3s so 0,2)
So we get 2,31 + 0,2 = 2,5 let's suppose our enemy has no armor (yet 4+ is not that uncommon) that's 7,5 wounds!!!!!!!!!!!!!!!!!!!!!!!!! (no armor, no ward for opponent)
THAT IS BAAAAAAAAAAAD for a HtH specialist, not enough attacks, not enough damage, not RELIABLE!!!!!
by the way 5 Blightkings (NOT HtH specialists) have 3A each that trigger d6 hits for every 6 so
15A at 3+/3+ you get 9,9 but you trigger 2,5 d6 attacks so 7,5 on avarage
so we get 14,9A on 3+ = 9,84 wounds
Blightkings have no rend so let's say in this case the adversary has a 4+, that is still 4,92wounds
So Blightkins that are a lot more reliable, have almost a double amount of wounds, an armor save, and cost the same are a similar HtH damage specialist, except that that's not what they are.
Bullgors need to become a lot more reliable, so I agree with you about 3+ to hit, 3A(at least) need 5 wounds (they are the beefiest monstruous infantry), impact hits (they are mad cows, how is it possible they don't have impact hits... Pamplona anyone?) and they can cost even 200pts but they have to be able to deal damage, a lot of it!
The same goes for a Doombull... Come on look at Ogroid, the skinny cousin: he fights better, survives better and is even a mage!!!!! Ogroid deals impact hits, a massive hulking Bull Lord no, he goes around as a happy camper dealing 3A! 3A, what kind of Hero is he supposed to kill with that? He gets eaten even by a Megaboss!
I'm not talking here only about meta, or power, it's also about the lore. Bullgors are supposed to be hulking monsters, even in Total War they are the most damaging monstruous infantry, or even in 7th/8th edition Beastmen were rubbish but at least Minos were nasty, and a Doombull was a true Murder Cow! I don't want Beastmen to be the top-tier army, but if I play a mad-cow party, I want to play mad-cows, not badly armored and equipped skaven!
