My in game name is acezora12, I've been playing Minecraft for about 2 years now so I'm not a pro, but I'm not far off.
To be honest, I haven't played much FTB, but I have played a lot of the Technic Mods like Tekkit, Technic, the new Hexxit, and many more. I've never really learned about most of the technical things, but my friend (in-game name Gingerbread_915) is very good with many mods, and I'm always willing to learn.
My favorite mods in Mindcrack FTB pack are the Portal Gun Mod, and whichever mod allows to have your items on your back. I feel that the portal gun mod adds a realm of efficiency to Minecraft and a new way to play. The other mod gives me a feel of realism as I have a pickaxe on my back walking through a village, only to pull it back out for a day of mining.
The thing I really enjoy about the game is how expansive it is. There are so many things to do and when you think you've done it all, there's so much more to offer, so much more to learn. I've always enjoyed that about Minecraft, and any form of it.
Whenever I go on servers, I never grief, use only that which I have permissions for, and do what I'm told. I hope that I may be able to join your server, because from what I saw, I liked very much.
