Even chess has more variety...and it doesn't lag, MD, or troll me with ALL CAPS DIALECT or smurfing or general asshatry....
Perhaps I've oversimplified things, so be that...sure, the occasional strategy involving HC or LRF spam might work...maybe you'll see a classic subverter+mine strategy pulled off, or some trolling with cielos or dominas....but at the end of the day, the game is Sins of a Titan....that titans are vulnerable at low levels does not change the fact that your entire strategy ultimately revolves around killing the enemy titan (else face it's wrath...and level ups)...
Whether that is a good or bad thing is a matter of opinion...but it's still sins of a titan...
