Siege techs are not used in the current meta, hardly see any player searching.
Techs are outdated for a23 and even more for a24, with the current changes in balance.
The benefits is below compared to cost, for example:
- siege_cost_wood costs a total of 1250 res and give -20% wood cost for siege engines. Siege tower is the siege unit that costs more wood (500). 500/5=100x12=1200. Need to build 12 siege tower for technology pay yourself. Similar to siege_cost_metal.
What the patch proposes is a fairer cost for techs, and give different technologies to civilizations.
