1. send all your engeniers to the mexes at beginning.... each for each mex point.. fast taking the mass is important (in replay you see enemie is much faster in economy this way)
2. dont group your egeniers for beginning, because your eco is low and its important for make it better (->nr. 1)
3. defence points make only sence for a small pass (build also walls around IF), otherwise its helpful and lower costs, making units (they are mobil) for defence enemie units
4. Radar and scouts are most thing, why you lose or win a game... 4.1 if enemie see your units faster he shot faster 4.2 he can send more units to the problem 4.3 he can bundle his economic in the right things->no wasting mass
SO build very fast a radar in your base and send scout land with your units
5. at 13min he bomb your units in front, all the time, but you dont build a air fab and build aa...
that the biggest failures you does
some little failures:
1. dont build tmd if its not needet->radar would show you this if you not sure about naval etc...
2. same with shild-wasnt needet
3. in real game attack acu before attacking base (mostly)
4. at this map you can send maybe 5 engeniers to middle->chose the 5 engeniers hold [alt]+waypoint->so engenier will reclaim all wrecks on this way...
at least: after you assure this points, look life replays in faf lobby->chatroom->roll mouse over a grade of a player->watch out for a >1000 player->watch out who of this have this two swords in the right of the name->press this swords->look live replay an learn
