I gave it a shot and it definitely seems like a better and less time sensitive method to taking that fort out, for greeks at least, plus it feels like a stronger opening for eco.
I always go eles as egypt (it's just an easy build), spam enough elephants and they do cut through the counters soon enough(armory upgrades asap helps), if you can focus down the stables / barracks initially you'll have less spears and promos to deal with.
