ok, so i noticed that not many people mastered this race well i havent either so ill tell u my strat.
(now when following this strat u must build close to where only a unit at a time can reach the back of your base giving burrows more attacks causing frustration
1.put 4 peons on mine with the fifth build an altar
2.build two peons in ur hall
3.with the first build an orc burrow
4.then with the second get a barrax,(make sure that u keep building peons till u have 5 on wood)
by this time the altar and orc burrow are almost done send the peon that built the altar to gold and the burrow to wood.
5.Now build a hero and another burrow,(i think that the bm or fs work best with this strat although the choice is yours.
6.now take a peon from wood and build anothers barrax
7.the other rax should be finished bye now so build a grunt and make the rax group 1 now your grunt and hero should finish at the same time take them and find the enemy base.
8.when you find it make sure u keep harrasing his army make them come out of their base now press 1 for your rax and keep building grunt at your rax(also when you have the resources and the time build a voodo lounge 4 pot)
9.also keep in mind that grunt take up quite a bit of food and more burrows will be needed so still build clustered but keep building the burrows.(also make a war mill and up the armor and attack of your units/buildings.)
10.now if your 5 grunts and hero didnt end the game this isnt your strat.
11.your best bet is to go stronghold get raiders and then go tier 3 and go shamans and raiders combined with some grunts or even tauren.(if you used this strat and lost more than 5 units give it at least two more games and if u still loose those 5 units this strat just isnt for u.(and never let your hero die experience for him is priceless. If he dies more than 3 times in a game not to be mean but u in my opinion are a no0b no offense and if your using the bm he shouldnt die once at all.)
In a bad game i loose 3 units thats all so that may give u an idea about where you should be in the game. BTW you must have outstanding micro to use this against NE because of wells. I am regularly a NE player so ill post another great strat for NE in time.
