What if UT could be researched in TC instead?
Remember the old Saracens castle age UT being removed and given for free to bengalis, it makes people realize that monk armor are actually OP if given for free.
Some UT are actually strong but held back by high set up cost of a castle. What if they could be research at TC instead, would it create more interesting strategies?
Should certain civilization be OP after this change, we could balance with the cost.
