did you use all your ironit in that gauntlet? it is TOOOOO expensive.
I did grad B to reach Grad A and stop here to have only 2 new talismans ( the only good reward in gauntlet...) after in grad A it is 6 SOW for each battle X6 = 36 SOW for 28X6= 168 IC
In PVP 36 SOW give me 540 IC and more level more big difference, actually it absolutely don't worth the price....
