Why is Carth Onasi in Ships Hard Nodes?

250 shards / 21 days = 12 a day.
375 energy for 3 refreshes per day.

There's 3 ways this can be done:

A) you have saved crystals and can farm hard, or use your accrued daily crystals to farm (easier if you place top 3 in either arena and/or fleet)

B.) you can buy the crystal pack that gives 2800 for £20. That will cover farming Carth at the rate needed above Per week. 375*7= 2625. You'll buy 3 = £60. That's a daily cost of £2.85. this method also leaves another 500 crystals left over after 3 weeks

C) you whale at the end on packs and spend circa £300

Juhani, despite being on a hard node is a 16 cost and easy to farm solely using accrued energy and taking 3 refreshes. So really you need to be making 500 crystals a day to farm both comfortably.

Obviously this only works if you compromise on all other toons for 3 weeks.

Your gripe seems o be it's paywalled. But it is and it isn't to an extent - it depends on your situation. Because I place 1st in arena, I can spare 375 crystals without needing to purchase
