Malians are (if played correctly) having a hard powerspike in early/mid age3, after aging up with the Grand Fulani Corral.
Almost noone these days plays into Farimba.
Since the powerspike happens in age3, THAT should be addressed.
Malians are vulnerable early age2, if they wanna cow boom and age up quickly.
The patch made them EVEN MORE vulnerable, which is far from ideal.
Now they are even more all-or-nothing than before the patch and their mid-late feudal game got a nerf.
The feudal was never a problem.
In my opinion, instead of nerfing the base-value of the cow-passive, the Grand Fulani Corral should have been nerfed, possibly even more drastically than the current nerf on the base value.
Right now, their super lategame, which already was on the weaker side, was negatively affected, while their semi fast castle became even more risky and their mid/late feudal weaker.
This is imo a the very (!) wrong approach.
The Grand Fulani could have been nerfed from 20 to lets say 15 or even 12 food/minute for every cow.
When aging up to age4, it the bonus could have improved a little or even gone back to the original value.
For deeper understanding check the graph for winrate/gametime for Malians in Conqueror level, ranked 1v1 from aoe4 world.
As far as I know, no data from the recent patch have been applied yet.
So, this is the PRE-nerf Malians.
Soon the Post-nerf values will be available, I’m expecting an even more punished part of the graph in the first ~10-15 minutes.
You can clearly see, that they tend to lose games in feudal age, if the game ends early.
This is their weak point when trying to cow boom.
Why punish that time-window even harder?
Instead, the spike after that should be addressed.
Which would be possible, by reducing the bonus of the Grand Fulani Corral in castle age and bringing it back up in Imperial age, where again the winrate drops significantly.
Probably even increase that bonus in Imperial age, while giving it a more noticeable nerf in age3.
Checking Diamond level:
My idea of a mild lategame-buff through improving the Fulani Bonus slightly in Imperial age, but reducing it for Castle age, would be great.
As Malian’s winrate spikes hard in early/mid Castle age, but falls off significantly in lategame.
Last but not least, the Farimba landmark could become more viable, once the Fulani Corall has a weaker age3.
