why the devs nerfed the Kipchak that much?!

As all of you know that at the release of DE the Cumans were the best civ in the game with their insane bonuses at the release, but they are now in the worst 5 civs in the game. However, I really think that the Kipchak nerfs were too much to be done at once, the Kipchak now literally the worst ranged unit in the game and the weakest one, when the devs nerfed this unit, they nerfed it at 4 sides at once, they nerfed the ROF to 2.2 which too high for a ranged unit, yeah it was 1.8 at the release but making it 2.2 is too much, the hp too got a nerf, frame delay got a nerf, they are literally the worst horse archer in the game, yeah they are cheap but still, the unit is too weak and need some tweaks. IMO at least the Kipchak ROF should be down to 2.0 (like the normal CA) instead of 2.2, the base attack should be 5 (6 Elite) instead if 4, 5 especially with the lack of bracer. In general the Cumans now is just one of the worst civs in the game, and IMO they lack of military options more than the eco options, they have nothing special for their military except their 5% more speed over any other civ, their range is bad with the lack of bracer, no supplies for barracks to their militia line and their camels have no heavy camel upgrade, tbf, the civ is one of the most boring civs to play with, alongside with Malay, Italians, Sicilians, Burmese and Portuguese.
