Are you guys sure your playing the same KAG as me?
For one, unless its capture the halls or TDM, not many archers waste cash on water arrows.
Arrow range seems fine, basically if they can shot you, you can see them, which is better gameplay then having off-screen arrows hitting you. Then again, if you want to do that, why not go builder, you have 100 wood without having to do anything at all - builder ladders up, gratz you a sniper tower that greatly increases your range anyway.
Gameplay speed changes are ... well, I can understand if someone hates it, I'm not the biggest fan myself. As for construction, it's really have a saw at home or go home and get one.
As builder and without and specific desire (I.e. if its full on blind assault, I just go right away - 3 stone blocks on enemy doors, 100 wood worth of ladders - can easily turn a battle), I normally destroy 2 trees and take the wood ( = ~700 wood <3 u saw), but also means that the re-supply cooldown has run out, so I grab the 30 stone form the inventory and let the tent fill in another 30 for a tasty 60 stone.
Mostly it's hybrid building, wood wood wood, some stone backwalls to seperate. So many people waste several minutes making one beautyful stone wall that falls after the first keg, bomb or bomb-arrow, while having a multilayer system upfront saves everyone time - time mostly wasted by minecrafters sitting in base fullfilling there dreams, but hey whatever.
