I will tell you with vs1v1 orc16,2v2 19 rank, first of all, 1v1 troll sea.
First of all, it is straight out of the trolls: a come up 5 farmers are mining gold, out of the first farmer to build a mill, and then out of the farmers to build a barracks (thought the barracks will be 10 seconds later than the mill), at the same time, a farmer in the mine out to build a hole in the ground, and then out of the farmer to pick wood, and then out of the farmers to replenish the mine, and then the second hole in the ground. This way, the hole in the ground mill barracks will be good at the same time, and keep on sending out trolls, and then replenish 2 barracks. 30 population climbing 2 books, 7-8 peasants picking wood. This tactic is generally seen in the case of orc vs ne, many people will have a misunderstanding, trolls are strong in the late stage, in fact, the so-called strong and weak is relative, the late berserk trolls are very strong, but ne's high level panda also appeared, it can be said that you will die very very bad. So once the ne bear deer technology tactics, must be as early as possible rush, can consider with tower (with good bull head of the aura, if it is 2 barracks, level 3 bull head must give priority to point 2 level of the aura), this wave of rush don't be too obsessive, don't necessarily want to push the other side, the main purpose is to suppress the ne hybrid unit molding, and high pressure panda inevitably can't practise, mustn't change the soldiers, operation Prioritize pulling away your own bloodied units. Shaman is not only useful for 3 books, many times Shaman's purification and fixation will be more useful than the hammer. If the opponent is a wind German, then out of 3 books of trolls, hair dark ranger, silence wind German, out of 4 or so soul walker, you can consider the master class witch doctor, not recommended straight out of the shaman.
If it is against ud, you can consider the regular opening, out of a big g to troll. Because of straight out troll, ud's early 7 dog limit rush will make orc quite passive. But barracks is just fine, speed 3 books, out a kodo, 7-8 berserk troll, 3 master shaman, 2 master witch doctor, pay attention to master level up and press early, don't out 2 heroes. If the opponent is a spider flow, do not be obsessive trolls, double barracks big g, speed 3 books, pure big g + trolls, open 2 mines, cement tower defense, and then out of the beast fence, soul home technology. There is also a misunderstanding here, the bull head must not learn trample, must be shockwave. 2 rounds can consider panda.
22 In the case of the opponent's double hum or orc, trolls are not recommended. Late heroes make the early stage to allies a lot of pressure, it's painful. Late combo group kill magic is even a nightmare. Of course you must fight, you can cooperate with the double aura of the elf white tiger, and take the economic route.
First of all these, hit the hands are sore, do not understand and then ask. The main thing is not used to see some do not know how to pretend to understand.
