This is from a Horde point of view but can be done from Alliance if you flip it around.
I will go over rules first then into the startegies.
Rule #1 NEVER go for the flag first. (If you do this you will hurt your team.)
Rule #2 Always go for a 3 cap to start.
Rule #3 Never leave a tower Unguarded. I know this is common sense, but you wont believe howmany people actually do this.
The name of EOTS is offense and pressure on your opponents. In most EOTS's you will see people rush the flag to start each team caps 2 towers and fights for the flag. Well that is gonna result in a 30 minute game and you might lose. If you like wasting 30 minutes in an EOTS which doesnt guarantee you a win, then keep doing that strategy.
Now for the strategy:
At the start you send 2 people to Blood elf tower and 2 people to Fel Reaver ruins. These people will cap and guard these towers. The rest of the team (11 people) rush Draenei Ruins or Mage Tower pick ONE at the preperation area and rush whatever you decide. We will use Draenei Ruins in this example.
DO NOT go in the middle for the flag at the beginning of the game. You will hurt your Offense if 3 people rush the flag. Those 3 people are needed to help everyone else take the third tower on your opponents side quick. Let the other team grab the flag thus weakening their Defense when you rush the tower on their side.
If all goes well, you will have Fel Reaver Ruins, Blood Elf Tower and Draenei Tower to start. (3 towers to thier 1) Once you cap the third tower, everyone on O
rush to mage Tower. The alliance will be scrambling to defend their last tower and or rezzing at their last GY so they will be busy fighting your Offense. This is when the middle opens up. The alliance will drop everything to defend Mage Tower as if they lose their last tower it is pretty much guaranteed game over for them. (Little do they know, once you 3 cap to start it is VERY difficult to recover, thus making them lose anyway) 1 or 2 people can now run the flag.
If you execute this plan from the start, you will win EOTS in about 10 minutes. This may seem like common knowledge, but you wouldn't believe how many people want to just rush the flag and hold 2 towers and trade flags. I don't want to spend 30 minutes or more in a BG. Whenever I see a game like that I do the Alt F4 wait 5 mins and log back in to get out and queue for another EOTS.
This strategy will work if your opponents play the 2 tower flag cap (Which most Alliance and some horde teams play) If your opponents play the 3 tower cap to start strategy, then you will be in a very competitive game.
So to summarize this strategy:
1. 2 people take Blood Elf Tower and 2 people take Fel Reaver Ruins. (Stay and Defend)
2. IGNORE THE FLAG
3. Rest of the offense take Draenei Ruins (with 11 people rushing it Draenei ruins will be taken very quickly)
4. Once Draenei Ruins is taken Push for Mage Tower and press them back into it.
5. The middle will be open so now is the time to cap the flag.
6. Enjoy fast wins in EOTS.
