I don't even get why this change was done, 75% nerf to certain blocks seems too much, it seems like another one of those "oh players have figured out a tactic that works let's get rid of it so they have nothing that really works" moves. I just don't get why, people still had to defend, use traps, use guns, had the horde coming up to them mostly in a tower style in a tower defence game. Next, it'll be "oh traps work, let's get rid of traps, perhaps guns need to just give them a tickle instead of actually shooting them"
