well i guess that we cant do anything this matter..
they should make another update to add razing ticks op to 5 ticks or limiting OP build 1-3 OP per tick.so OP maker cant build much more and should wait another tick to build again ahahaha
maybe this was a good idea too...
Lolita, I mean Ilona herself has made a topic about this matter. And we've discussed a lot about how to prevent farming OP, several ideas was thrown out: limit the number of OPs made per tick, limit the number of OPs by the number of units, etc. But all of them has been shot down. Look for them in the Suggestion Topic.
