@XVX: btw I'm now calling you XVX its quicker...
but anyway, that is basic strategy that Gaia will almost always do vs. Loki on certain maps (Alfheim being one of the only ones you can play rated on anyway) so he won't disagree to disprove you, more to say "HA I'M HELLSRAVAGE HEAR ME ROARRR" and as for the FT/wonder, this works vs. Loki (when done with PRECISE EXPERTISE!!) but its very hard to pull off, Loki rush = Infantry Heroes/Myth units, neither of which Gaia can do much to take down...
HOWEVER, neither of these are viable in Kronos vs. Gaia because if you try to FT you will be owned by his classical attack, if you try blocking with Gaia forest trees he will just timeshift his military buildings over, and claim the trees for himself...
best usage of trees is protecting towers or placing beside the corners (with your market in the corner) so there is a small space for caravans to travel, but not so small that they get stuck, (takes practice but you get used to doing it) because then it becomes simple to protect market, throw some towers inside the trees, wall up a bit, make a couple gates, then you can just woodcut from the inside until you start to get too thin wooded there.
