First of all, if you wan't others to help you with armor/their opinions which is the best for them, tell us what Character you got by Profession, Male/Female? And also, which other campaigns can you reach/if you can any others.
Armor is the thing, that player should decide on their own. People can tell you which armor they like, but the thing is, wear the one YOU like and color YOU like. Same for Weapons.
Prices depend on which armor you like. If you like 1,5k armor but you wan't to have elite just to look prestige, that's not the best idea, because you'll spend money on armor that you don't like the best.
Normal Armor (1,5k) - Cost: Amount of specific materials and 1k per armor piece, ~10k alltogether.
Elite Armor - Cost: Bigger amount of materials than normal armor/more rare materials than normal armor. 15k per piece, up to ~100k per armor.
Obsidian Armor (Most expensive) - Cost: For every profession WITHOUT headpiece (casters) Obsidian armor cost 105 Globs of Ectoplasm, 105 Obsidian Shard and some specific materials for each profession. If you got a profession, to which Obsidian Armor offers headpiece, it's an additional 15 Globs of Ectoplasm and 15 Obsidian Shards + materials specified. Total price atm is ~1,2 million, because ecto prices raising.
