Actually when im greek in a 3v3 game I usually go for damage sponge and tribber.
This is the way I work it. Lets say I draw outside position. I boom, with the risk of being rushed, and hit a mediocrely late bronze with bowmen guarding my woodies. I make navy, to protect my fishing fleet...but I dont care to engage in boat wars just yet.
The guy in the middle comes and covers my flank a little, but he boomed hard too so he wont be massing units for a while. Now I will trib resources to the other outer guy who probably took a smaller boom or rushed, and I trib him a lot. Middle guy and me combine forces on my territory and push off the guy nearest me. Now I just spend all wood on TCs and villagers and boom like a madman. One time with greek (in a 3v3 game, all with players that were very good) I boomed to 70 vills in 20 mins on a cont map. I had woodies all over the place, and I was tribbing literal thousands of wood to my partners who just made the biggest CA masses youve ever seen. I mined a little gold...but not much. Instead I had my partners trib me gold, while I tribbed food and wood. I had so much wood, I just laid down a few seige shops and built some stoners to accompany my partners stuff. I never made a strong greek offensive, instead I sat back, tribbed, and just complimented their army with stuff. I went hard navy with all the wood I had, and owned over half the enemy water easily, with another 1/4th being fought over with me winning. I kept tribbing, and never ironed.
Ironing isnt necessary sometimes. I mean, granted, greeks have a nice iron. But instead of ironing and slowing down my resource intake and trib output, I didnt iron and tribbed almost everything I had. I kept the bare essentials of food for me...enough for new villagers and upgrades. At 30 mins the game was over, easily. I never ironed, never wanted to. I never made stable or academy units. Just stoners and bowmen.
The way I see it, stoners and bowmen really arent so bad at base defense. My greek stoners took out all enemy archers, while my greek bowmen took out any enemy melee units. It worked out ok...although I never really destroyed anything (although my ships did, and my stoners that followed my allies armies around helped some), without me in there they would have lost. I think thats a great way to play greek. Forget offense, cause you just cant do it until iron. Iron jumping is useless in most every game I play.
I say sit back, enjoy your economy, trib to your allies whenever they ask for something. Wood is the key though. By me tribbing over 3500 wood in less than 25 mins, my allies had enough wood to mass huge CA armies and then some. My enemies, who underestimated me and my greek, never really attacked me, because they never really saw my military...and when they did, they just didnt want to bother with me cause I only had bowmen and stoners (which are not a good offensive army).
If the game lasted another 5 minutes, I would have had plenty of food to iron. With 60 some villagers and 30 fishing boats, I would have had a powerful iron.
