the best strat?
flanks=archers and pocket=cav .
Going fc is a **huge** nono in arabia, at least when people are playing top tier civs , if its a random civ game then PROBABLY in some cases u can ge away with it but its still a bad idea anyway and u have more chance to win playing feudal.
18/19/20pop+loom uptimes to have an agresive feudal,flanks should go 2 range archers and pocket stable scouts into knights/camels( the pocket can click to feudal without loom, its risky but it pays to have 1 extra vil in the uptime while doing a tight opening, ofc u need to research it asap when feudal).
The pocket in a 3v3 need to have a good map awareness to carry the game, the simple way to play is 2guys on the worst map side or worst matchup side and then let the other side 1v1 and at some point switch or send army and generate some unballance in that 1v1 side.
Gurjaras tend to play long feudal with upgrades because they can mass camels in the uptime to castle, if u have knights against camel civs ( like franks vs gurjaras or indians) your job is to dont let your flank die because you cant kill camels but archers can ( flank civs with thumbring are way better against camel civs)
Thats basically the meta, at least from what i studied in the lattest weeks ( since the NC was anounced there is a lot of high elo Tgs everyday) sometimes i join one of my country teams when they need 1 player to get matched against a specific team ( is not even fun to play at that lvl when u are not even close to their elos, this guys are averaging 2k3+ 1v1 elo which is nuts for my weakass lvl)
sry if my english suck
