It seems they have fixed the issue now, i just managed to buy gems with a Visa and i got the popup screen for mobile authentication. (I live in Norway btw)
you can wear both 1 Conflux and 1 slumbering conflux at the same time, because its unique by name.but you cant turn the animations off, when you craft the conflux with animation its permanent.
The reason anet even added reward tracks in WvW/PvP was because you almost got no loot or reward from any of these contents (In WvW you would get just a few champ bags if you capped some stuff or lootbags if you were farming the enemy but this is very inconsistent).so you would reward pve with even more loot and make the reward totally unbalanced and unfair towards WvW/pvp players
