I did not see any posts about this launcher. Its like the FTB launcher, however it has many different packs. My favorite pack is the Madpack by Twitch streamer "Jonbams". I just thought I would mention this launcher to add a bit a variety to any MCers that might be looking for something new. Enjoy, I know I love having an alternative to FTB.
I see the ATlauncher has the new compete yogcast pack with 200 plus mods. Some look pretty cool but its to many mods plus i am already using 3 different launchers.
Glad to see someone mentioned the AT Launcher My favorite is the DNS Techpack 1.6.4 it's a mature pack and has a grey listed server so a lot of the bugs have been sorted out I would go as far as to say that it's the best tech mod pack out at the moment.
