Upgrade on strength to get more off dancing, you'll make more plunder if your intel is lower. You'll just have to use a pot or two.
No, if your stats are smaller on intel and you're hitting a farm with bigger intelligence the plunder is higher. I use to think the same until a few old school player's taught me about builds.
Being heavier on intel only makes it easier to hit dance farms. If I hit a lcbc, I'll make the same amount no matter what their build is. So you will not make more if you have higher intel, it'll just make it easier to hit dance farms.
