New greenskin technologies that apply to goblins do not affect night goblins. I can understand they do not act on wolf riders, spiders and squiggles this is cavalry, although still it does not make sense given their stats. But the night goblins? With an upgrade of +7 armor and a bonus from the Shaman for +15 + improvement for scrap, we have 72 armor goblins versus 15 armor night goblins. In the compartment that goblins have 10% more replenishment from technologies that, again, do not work on night ones, it makes no sense to take night ones at all. They lose in stats, they lose in replenishment, attack and defense. They cannot be upgraded for scrap. Perhaps you will make sure that goblin technology is applied to all goblin squads and not just to spears and arrows.
The second problem. Skarsnik and Goblin Lord. They had a skill that increased by +12 attack for goblins and night goblins, you replaced it with +6 attack and + 20% charge for night goblins! 20% charge for goblins? You are masters of jokes. Moreover, the Shaman now has +6 attacks and +15 armor skill. Perhaps to all goblin Lords, like Shaman, Skarsnik and Goblin Lord, will you give 1 skill that gives ALL GOBLINS +6 attack and 15 armor?
After all, 20% of the charge gives a total of 16 charge bonus, which is terribly small, especially for goblins which are used as a meat shield, and not the unit that cuts into the enemy from the charge. It just doesn't make sense. A meat shield needs survival, not a charge. And I hope you reconsider the attitude to the technologies and skills of the Lords so that they increase the efficiency of all goblin infantry, and not spend time studying heaps of technologies that, as a result, give a bonus to 2 units, making their higher tier counterparts useless.
