The evolution of building has a very unseen point, simply because the new players have not quite moved forward, while people who have been around in public beta for a while have experienced several generations of building. Each a new thing to the steam playerbase. Let me introduce you to the current pinnacle of cancer in the building world, and show you how to use struts instead of mashing back wall. As a builder, I had an issue, I needed to make things that delayed knights and could stop bomb jumpers and help my team kill them, I needed to cut their mobility, and find a very resource minimal way of delaying attackers, and also allowed my team full mobility without being slowed down exiting the base, that required no time or thinking to place. Thus cancer towers were born, named cancer towers because they are literally cancer that can stalemate matches quite easily. They do not burn very well thanks to the stone backwall, they allow archers to fire out of most of it safely, and knights can exit any point they desire, and their scaling is durable enough to stand after attack and not allow the enemy to go up barring luck in door damages. As you can see the cancer tower is wood platforms, with stone underneath TO STOP BURNING, and the fact theres so many means bombjumpers get jammed somewhere, bombjumpers also cannot move through the doors. The doors allow you two ways of moving up next to the ladders, if a enemy tries to move up by breaking the wooden doors the ladders break, and if the ladders are broken you can still climb using doors, they also serve as extra delay. The struts connect them all to each other insuring their structural integrity is horrifically robust as well, while spending little in the way of resources. Below I will demonstrate some forms of damage that may occur. CATAPULT ROCKS~~~~~~~~~~~~ 5 SHOTS As you can see the rocks were going through and hitting the stone structure instead of destroying more of it. BOMB BOLT BALLISTA~~~~~~~~~~~ 12 SHOTS As you can see the shots failed to destroy the second door section, the bolts would simply fail to do damage against some platforms, or fail against the doors. 5 KNIGHT KEGS POINTBLANK AGAINST WALL~~~~~~~~~~~~~~~~~~~ As you can see, I used 5 kegs one after another pointblank and struts still allowed it to stand Not much stops a keg but this survived it. So as you can see, this tower truly is a minimal resource, cancer that can consume the landscape quite fast. The only real counter to it is regular knights slashing and throwing regular bombs at it, and it is doing its purpose delaying until its destruction standing tall gloriously until the end, like the rest of the structures that are built.
