Please tell me you're not genuinely this stupid ....lets assume you actually were really smart, instead of only trying to. then you'd fastly realise that your random math doesnt make any sense at all and that the ore puri is probably the best RA2 building.
1. i hardly play allieds but im pretty sure the ore puri doesnt take more than 1 allieds power (unless you counted tech with, which wouldnt make sense aswell, since you also build tech for other reasons/things).
2. what exactly does the ore puri do?
we all know it gives you extra money for each load, but how?
do the miners work faster? No
do the miners mine more? No
so what exactly does it do? it gives you extra money for the same speed/amount mined.
what does that mean? it means that for example an ore spot worth 60k, automatically is worth 75k for an allied player with ore puri, thats 15k advantage on a such spot.
i know in the end it always matters on the situation, spot and map.
but im just trying to say your comparison doesnt make any sense and you just did some random math.
Of course if you get to the situation in which the entire map is mined out, assuming you got the purifier early enough, you'll have had an advantage.
The entire point of what he said is that if an allied player does go for a purifier, the allied player has to sacrifice so much early game that any half decent sov player is just going to go and kill them.
