I'm maxed IA except walls, armory researches and uni reasearches so I focus on proper distribution of my workers between all leaders so I can upgrade all leaders at the same time without idle workers. For example I still upgrade some at level 1-2 and some at level 3-4. Mansa Musa will perturb this order
I know that all my workers will be sitting at uni for another year so I don't care what I upgrade first, because before advancing to GA I want to research all leaders and all armory researches plus maxed all my walls. I think this will provide me with huge advantage for next ages
I already steamroll EA bases within 1 minute
and I crush IA and rushed GA players with only my normal troops.
Although I admit that playing that way and waiting ages for free workers to upgrade one wall piece makes game boring like hell and don't need much raiding
On the other hand I've started playing other games
