There word isn't the law, however they are higher ranked and more skilled than you are.
Running in a water and a fire before 2 min into the game is pretty hard seeing how you won't have an early game army. If you don't have a decent eco you're at a severe disadvantage, and you won't have a good eco because you're trying to maintain tower with units and at the same time, run in a water + fire. So if you actually manage to land a hit with blast that early, you'll still be at a disadvantage since you most likely sacrificed your whole army to blast his miners. He will most likely take tower and your eco will still suck.
Getting a cycloid to stun archers? Good luck with that, I've seen many ele players try stunning archers and blasting them. It doesn't work, archers should be able to kite your water and fire before cycloid gets into good range, an order player who knows what he's doing should have a wall in an OvE.
An inferno fills the role of getting rid of low health units better. It's cheaper than getting a Cycloid, water, fire, and tank.
