What's up with people that are looking at this leader addition from such a shallow perspective?
Anything that doesn't directly buff your troops is apparently useless?
Hunting and harvesting will now take only 2 seconds compared to the previous 20! I mean, I guess you liked sitting down and waiting for these timers to tick?
50% more resources from farms and caravans, on top of the 40% permanent increase. It means more loot for everyone when raiding! Useless right?
Vault capacity is also apparently useless, even though putting 4000 more oil in reserve is a nice touch to save you just slightly more oil from raids and also give you more oil if you collect 24 hours. Not everyone is a raiding machine that has all day for oil raids you know?
To connect to that, increased capacity for oil wells means you'll actually get to collect the oil that you make, given with Amelia research and the permanent buff to production, oil wells overflow in ~5 hours. Again, some people get a large percentage of the oil from their own production. Plus, more oil pumped in the game for everyone to raid.
Admittedly, double the resources from hunting and harvesting is very underwhelming and it would've been better if instead this had chapters concerning worker reductions for those activites.
So there are the "useless" researches.
