There's no point in preparing any guild for progression raiding in this game. BW themselves stated that they will not be concentrated on Dungeon/raiding content in the endgame and will most likely focus on the story-driven content like the rest of the game. As the Operations are now there are a TON of bugs, from bosses resetting to chests not opening after a single wipe.

Where PvP is concerned, it seems Open World PvP is highly discouraged and the upcoming patch BW is planning isn't going to solve much. Currently Ilum is a mini-game, where Republic/Empire are just trading bases for the daily quest. LAWL!

They'll get the PvP right eventually.
