Let me know if my math is wrong. 1 Rank = 2,500 1 Heavy Synth = +25 3 Heavy Synth = 1 Strange Coin 1 Rank = 100 Heavy Synth 100 Heavy Synth = ~34 Strange Coins 5 Motes = +100 1 Mote = 2 Strange Coins 1 Rank = 125 Motes 125 Motes = ~64 Strange Coins 25 Ranks = 62,500 2,500 Heavy Synth = 25 Ranks 2,500 Heavy Synth = ~834 Strange Coins 3,125 Motes = 25 Ranks 3,125 Motes = ~1,564 Strange Coins [b]Please do not purchase and trade Motes of Light from Xûr to level up your factions. Instead, purchase and trade Heavy Synth from Xûr, Eris, or Variks. Motes of Light are a great way to rank up if you have enough of them. They are easier and faster to accumulate than Strange Coins. Essentially you are better off exchanging Motes of Light for reputation, but if you plan on buying your way up to rank 25 then purchase Heavy Synth. [/b]
