IC2 used to definitely be one of the core tech mods. But now, just to add my bit (because I can ), we have many replacements. TE does wonderfully at autosmelting and doubling of ores AND handles BC power in a great way, Powersuits takes the place a weapon with high damage and durability, and then you still have the ability to add other features to it, whereas with IC2 you had the (diamond) drill and chainsaw. Oh, and crops that give you extra materials (gold/iron dust, etc...)? Forestry and extrabees. Honestly, I only use IC2 itself to power rotary macerators, induction furnaces, and my AE system, as well as my Gravisuit and Vajra (which I'm considering swapping out for MMPS). And I'm sure if you really want beer in MC you can go find a mod somewhere that'll give you that.
TL;DR It's not that much to read. Stop being lazy and read it.
