Yeah. Get 5-6 slingers by turn 15-20 with Mining first (to chop two forests), Rex up to 3 cities , save your money, upgrade your slingers, and then spam Ptati like no tomorrow. I lost 2 Pitati while killing TWENTY FIVE LEGIONS, various spearmen, archers, and warriors and taking 4 of Rome's cities. The only person you can't rush with ease in the early game is Scythia and that's because of their spam. Walls? Pffffft. It takes 6 Ptati 1-2 turns to take down a wall. What people don't realize about the Ptati is that once you hit critical mass, they're even more efficient than Scythian horsemen. You think Knights stop them? Think again. 6 Pitati shots kill a full health knight. 5 kills a full health legion. If they're upgraded (and most of them will be) it only takes 4 shots. 3 shots will kill pretty much anything else. They should rename the Pitati "the death machine" so people would build more of them and realize how OP they are.
