I have a question about the 2nd class q also.
Quest reward rates are x3 as in Server Information topic "Quest rewards: Exp х3, adena х3". I have done all three 2nd prof quests, got three marks from them. Then i proceed to do the shortened class quest "Good Work's Reward". There I am of course asked to give a Trader 3kk for a potion. After fulfilling the quest i am rewarded only 1,8kk (having all 3 Marks!). I should at least got 3kk, not even mentioning the x3 reward.
What is up with it? I feel kinda robbed and sad

Couldnt buy them RURs cheaply and am sitting here crying.
ed. trying to answer project's question - rewards in class quests are x3 - both in adena and exp. I got like 2kk form all 3 quests and 7 lvls.
