Now, the 1.5 update has changed alot. I have seemed to notice that it laggs a bit more, but is a very good update. For me, it has made maps such as Super Hostile very hard now that skeletions shoot fast when your near then, I died so many times on Waking Up -.- At the start to.... Anyways, for me it made skeletions a bit more realitic, since if you were up close, you would rapidly fire. It also made caving and conqeuring dungeons harder, and funner. And in the same update, all this redstone stuff came out! I play on a server, and it has allowed me to do so much more contraptions! Like lighting redstone lamps around the roads of my city at night, and it's AMAZING! At the same time, I died of starvation since my wheat farm broke -.- Thats how the update effected me, please post on how it effected you! Thanks =)
