Eclipse was created with the goal to cater to as many players as possible, like you.
While medium in size, Eclipse contains some of the biggest names in Minecraft modding. Many kitchen sink packs include two mods with repeat features, or small and niche junk. By removing that, it's been made so that you don't need a super computer to enjoy a massive amount of content. The performance conscious design as well as the large number of things to do make this pack perfect for small to medium size servers.
The all-around nature of the pack offers progression paths to wizards, scientists, blacksmiths, and chefs alike with mods such as Thaumcraft, OpenComputers, Tinker's Construct, Pam's HarvestCraft, and many more!
