Im new here but I really like it. So here it is, my combo attack strat. If the player go's hardcore ogres, then you make about 25 ogres and 8 or 9 dragons, while your dragons rape his ogres he will make throwers or archers, then you unleash your ogres to whip his ass. and thats how its done!

The problem is when you are playing someone of equal skill, you won't have the time or resources to outproduce him wiht dragons.
Plus, a good player can easily take down dragons with death and decay, making you waste more money than he did.

If you can get a dragon (yes just 1), then you can go hit them and scare them into some towers and archers, and hopefully it will cause you to come out ahead on ogres.
Don't let your dragons sit around though, they really do suck on offense (they will be killed before you know it). Dragons are best used as defense to scatter grouped ogres or pick off the odd ogres here and there.
