Hah, I say unto you, HAH!

Try 270-300 company leves if you want your full sergeant set. That's right. ~300 leve allowances are needed to get enough seals to get the full set. There are 6 pieces, each one 5000 seals, so 30,000.

At ~100 per leve, well, you can do the math. Also, it is worth mentioning that the gear isn't even all that great. But if you want the full set for purposes of finally feeling a smidgen of lore and being truly involved with your nation of choice, that's the price to pay.

Stop complaining!
