I agree with you regarding eco advantage spam and defense. I’d like to add that the Nests can be strong for a push too and then it may not be easy to kite with Culvs and Springalds.
Looking into Vortix game history: he is overall more successfull with China than with other civs (not his best civ but a good one). Match count is higher: more than 30 games with China in total (3 accs). From what I have heard he is specialized in certain civs. I found one loss with China. His game history is relevant as he is playing against the most competitive opponents. When looking at the top 10 players China does not seem to fall of compared to other civs like Dehli or Abbasid. Meaning it is overall competitive. That does not mean that nothing should be changed.
Zhuge Nus are not supposed to counter Siege and yet they are still able to kill everything in masses. In your example you say the resource equivalent cannot be compared - agreed. Yet, Zhuge Nus somehow lose a part of their vulnerabillity as soon as they are massed given that they are ranged and harmonize well with spears. They have good stats and on top of that are super cheap to produce.
The scouts/ w-scouts and the Horseman are meant to counter siege and I can say that the scouts have extreme difficulty to do that in Age 4 as soon as there is a small number of Nests of Bees.
culv cost now almost 3 times the gold of a Nest of Bee in future 2 times and cost 50% more wood for one. Culvs are produced in most cases reactively as they only really serve to counter siege. The opponent can build 2 Nests from that amount of gold whereas his contractant can build only one Culv with wood to spare. IMO the potential harm a Nest can do is higher than a Culv as you can use it more widely and actively compared to a Culverin. How many shots does a Culverin need to destroy a normal Nest of Bees? 1? If so it is a good counter.
Still, should it require so much gold to counter an affordable unit? With 600 Gold you can build 6 knights and harrass or produce 10 Sofas and play actively.
Please do not get the impression that Horseman are useless against Nests in the following paragraph. Your point is understood…
I don’t find it good that when going Horseman or Scouts to counter siege the player has to think of and produce at the same time the counter to their counter, which again is countered by the Nest of Bees. In such a case the unit production for the counter to the cavalry counter has to be included in the the cost equation to fight against the Nest of Bees given that the losses if this is not done are higher. Adapting to produce archers against the spears fills the production line. The enemy usually attacks with several unit types to which production has to be adapted. Generally speaking, when fighting against other types of units you can rely on the counters for that unit.
This is not enough the case for Nests of Bees IMO
Please correct me if I am wrong (full techs no civ bonuses):
Spears vs Horseman: 5.15 strikes to die + spearwall stun/ first strike
Horseman vs Spear: 12 strikes to die
Horseman vs. Nest of Bees: 6.47 strikes to die
Scouts vs. Nest of Bees: 7
Warrior Scout vs. Nest of Bees: 7
Nest of Bees vs Archers : 1.49 strikes to die (all projectiles) + AoE damage (multi target possible)
Nest of Bees vs… Spears: 2.44 strikes to die (all projectiles) + AoE damage (multi target possible)
Nest of Bees vs. Horsemen: 3.38 stikres to die (all projectiles) + AoE damge (multi target possible)
Nest of Bees vs. Scouts: 2.9 strikes to die (all projectiles) + AoE damge (multi target possible)
Nest of Bees vs Warrior Scouts: 2.9 strikes to die (all projectiles) + AoE damge (multi target possible)
Looking at these numbers I do not have the impression that the Horseman & Scouts counter the Nest of Bees. This comparison is before considering clocktower nest of bees and S5 buff. So basically with a minimum of 3 Nest of Bees they are handling the counter by themselves theoretically and this is also what I have seen while their actual counter needs 7 strikes to destroy one of them (that is probably why you said 4 horseman → 2 strikes) provided you get through. And this is the problem: 4-6 Stables can turn out to be insufficient in such a case given that the scouts and Horseman get stopped before. In addition, Dps is getting less relevant from 4 nests upwards as all these cavalry unit types get one-shot.
I am not saying Nest of Bees are unhandable but I hope you see that they are strongly favored and can create balance issues as soon somebody is short on gold. In a clash of masses the Nests of Bees are able to reduce 2 of their direct counters to absurdity.
This is why I do not understand or support this buff.
