Well, true, you got a point.
It does require some coordination to tower-rush an oponent as Mongol.
The problem I personally have with that strat, is that it is far easier to execute it than to deal with it.
Which shouldn’t be the case.
As I mainly play Malians, Mongols have 64.5% winratio in Conqueror against Malians, mostly due to tower pressure on pitmine, followed up by either even more pressure, mass bow/keshik age2 due to double training or a mix of that and trade behind.
Since you are tucked in in your base and struggle for getting any ressources or saving your vills and especially pitmines/houses, the Mongol can mostly feel free to trade through Silver tree.
If you step out of base to disrupt his trade, he can quite easily catch you out of position with Keshik/archer and the speed arrow of the Khan and whipe these units.
If he’s losing the fight (which shouldn’t happen), he can just run away.
Because you won’t be making Sofas so early in the game (inefficient age2 and expensive when your eco is under heavy early pressure), your army will be less mobile than his.
The houses only costing 25 wood, having a small hp pool (previously even less), doesn’t make it easier.
If the Mongol player burns them, he gets a quite significant eco-boost in early-game, which accelerates his age-up, his early Keshik batches age2 or whatever he needs the ressources for.
I’m sure Malians are not the only civ to struggle with this strategy, though they seem to be one of the easist victims.
Meanwhile Mongols have a 53.3% winratio in Conqueror level.
I don’t think the 80->70 stone/minute dark-age Ovoo nerf will change this too much.
That’s a 12.5% income nerf on the Ovoo for dark-age.
Considering the training time for spearmen, the time your villager takes to walk to the stone-vein and to build the Ovoo, you are getting your first double-batch just a few percent later than in last patch.
The double-training for spearmen costs 80 stone, which means you have to wait around ~8.5 seconds longer to get enough stone for each batch.
That’s hardly a nerf honestly… Maybe for conq3+++, not even sure about that.
