I'm new to the forums, but I'm a veteran FTB player, starting around the time Mindcrack was created, and never quite putting it down. More recently, I started hosting a server with my friends for the Direwolf20 1.12 pack, and after hours of gameplay, I have some feedback. I'm a tech person, but some of my friends use magic. One of the first things they noticed was that, apart from many new mods, there were few useful ones. Getting to a useful point in Astral Magic hasn't happened for them yet, and probably won't. What I noticed, later on, was that the recipes for some Advanced Generators parts require IC2 components. Those generators are all I have ever used IC2 for. Many hours later, everybody on the server agreed that IC2 should either have RF-EU converters built in, or should be removed entirely. There are some other issues that I found in older modpacks as well. Immersive Engineering machines take up insane amounts of power. The improved blast furnace takes 64 EU/tick, and, based on redstone furnace efficiency, the arc furnace is useless. The diesel generator is on par with the efficiency of the base combustion engine, but cannot be upgraded and has just over half the efficiency of the aforementioned Advanced Generators. The excavator uses more power than any quarry and has more limited use, and the fermenter/squeezer also use too much energy per process based on their forestry equivalents. Additionally, the resistivity of all Immersive Engineering wires is too high to use over long distances, which is the only time when HV wires are useful. I love the new DW20 and all mods listed above, but they could use some work.
