Battle eles are already such an investment to upgrade and create, why you want the tech to be that expensive, is dumb, Tusks Swords is a stronger tech and is cheaper in comparison lol.
I get if is an Imperial UT, then it needs to be priced accordingly, but not that price, something like 500f 350w is fine. Burmese lack any food bonus and the tech needs to be accesible.
Speaking about Battle Elephants, I think their trample damage should be increased from 25% to 33% because they feel a bit ineffective vs Knights lol
