The problem I have with this is: NCsoft made a statement here on the forum saying the cheaper upgrade cost is only available until the next maint. They didnt say "dont upgrade through that path, we will delete your weapon anyways". For me it sounded like they are fine with us upgrading through that path until maintenance, why else would they throw out such a statement if not to inform people that they need to hurry with that path? If they didnt want us to upgrade they could have just ninjanerfed it and everything would have been fine. This way they baited a lot of people into their next level troll.
I wasted so much gold on materials and only got the crystals back. Support cant help me "because they got crystallized too long ago, referring to their token based restoration troll".
Well those Trolls working in the "Support"team finally convinced me to deinstall this game, so I guess they saved me a lot of money.
