I saw that somewhere else a day ago from you XD
Say the Order player waits for a second sword, so now it's 2 swords + Archer vs 2 Earths + Water with equal eco on both sides, the two earths could stun spam the two swords with the ice to freeze the archer, with next to no counterplay. However, if the order player sends both swords after the ice/water unit with it's archer running for its life to its base, do you think the order player can get enough damage out on the water unit or lead it far enough away from the earth units to take it down before the earths show up? Earths are slow right? Please tell me they are slow XD
Earth is slightly slower than water I think, but still around equal speed to a sword, and Earths can be built in 4 seconds, so the Elemental player will get a second Earth way before your get your second sword (12 second build time)
How fast are the water elementals? i.e., are they faster than archers? If not then the archer can just kite away from the water while the sword takes on the earth, but if waters are faster, then earth+water will destroy sword-archer.
Also, what if you got earth+water then got both miners to pray until 100 mana, then combo into a treature and focus on economy? Seems like it would be incredibly hard to beat, especially since order only has swords+archers at this point, and you can get easy free harassment.
Water is slightly faster than an Archer, trust me, I tried to kite one and I only got 2 or 3 shots in before I got frozen.
