Respec costs is extremely high in campaign

Hi, trying new Huntress but guess what, now my passives were not planed out before launch (could't dahh) so i did some misstakes. Guess what I don't have gold to respec even though i saved a lot of my gold...So tired of these high costs in campaign, why does it have to be this way in campaign???? Now i am stuck so either i farm for multiple hours to get the gold or I create a new character and then I have wasted 11 hours, just great...really makes me want to stay and continue playing this game...
