Yea, enigmatic weapons are from BT boss, armor is from Fane. With the Fane boss there is a 1/3 chance that it will drop armor for your class. With the BT boss the chance is much smaller as there are 8 different weapon drops and also a chance that no enigmatic weapon drops. BT boss is also much harder to beat, especially if you're doing it with pugs. I'm rather curious of what's the % of groups who actually finish the last boss as there have been quite a few times where the party I've been in has just failed to kill it and people have given up.
There have been people in my party who have gotten their weapon on the first run, I've yet to get mine after 18+ runs.
The Fane boss doesn't have an exact 1/3 chance to drop Metal, Leather, or Cloth. In general, the boss drops Leather and Cloth much more frequently than it drops Metal. I ran Fane for more than a week before giving up and just buying my fucking Quietus Plate.
The BT boss doesn't have an exact 1/8 chance to drop each weapon type. After running BT until I was bored sick of it, I just bought my fucking Aestivax. Running BT is fairly routine with my guild, as everyone knows what they are doing and are all generally Fane-geared and have their BT enigmatics and just doing it for enchant fodder, but that doesn't make the drop rate any less shitty.
Fortunately on VoT item prices are generally very reasonable due to heavy server population and lots of people running these dungeons. It was much easier to buy the stuff I needed rather than continue to bash my head against the shitty drop rate over and over again.
The problem now is trying to enchant all my stuff, having spent all my gold on the gear itself I don't have any left to actually enchant everything past +6, since you need to buy 12 Refined Alkahest per attempt past +6 and that comes out to 252 gold per attempt. I've gotten the axe to +8 but I heard the chances of +8 to +9 are very bad, on the order of ~10%, which means on average someone needs ~2,520 gold to to get to +9. Grinding for gold at endgame is an intense form of suffering. Gold rains from the sky onto you starting around level 40 all the way until 60, but then the gold supply just dries up.
The game has been heavily Westernized from 1-60, but once you get to 60 you are facing a seriously Korean gear grind. My reward for actually enchanting all this stuff, mind you, is to run Hardmode versions of the same dungeons I've already been running. I'm actually not sure what EME was intending by making it so easy to level from 1-60 and then having nothing for you to do at endgame except run a couple of dungeons and do dailies. Everyone hit the cap in a week, ran the same 2 dungeons over and over for a week, and then Diablo III came out and the servers have all emptied. I refuse to use the IMS to look for groups, because I'm a zerker and that usually means waiting 2 hours for the queue to pop only to be instantly kicked by the lancer. So essentially I log on, look for a guild party, get some guildies together, run my 2 dungeons, nothing useful for me drops, I'm too poor to continue enchanting my stuff, then I get bored and log off. I'm planning on keeping my monthly sub for 1 month just to get the Golden Dragon weapon skins, but after that there is literally no reason to keep playing until they start patching in the Korean content which was left out of our NA/EU release.
In terms of releasing an MMO against a stiff competitor without thinking through exactly the timing of progression and the endgame, EME pretty much blundered as much as they possibly could by putting Tera against D3 and also not having all the Korean endgame content ready to go at launch like BGs, Training Ground, and Nexus. There is NOTHING TO DO except run Fane of Kaprima and Balder's Temple at endgame and do dailies, unless you feel like going to get your ass handed to you at Kelsaik's Nest. Crystal prices being what they are, going to Kelsaik's Nest to die repeatedly will easily cost you hundreds of gold until you either kill him for nothing good (his drops are the same as the robot's from BT) or give up.
