I don’t know.
To me gold in the game is the most balanced thing in the game.
I rember the very same complaints about gold (and the gold iap) in WHQ1.
Same in Hunters.
I think nobody has even bought the gold iap, yet everyone was able to play.
After a while the gold iap discussion vanished.
My last WHQ hardcore run clocked 43 hours, and I had like 100K gold.
In WHQ2 you end both campaign around level 6 (more if you play many white quests, I had one run at 13) in way less hours...there was nothing I couldn’t afford.
You get 200-400 gold per dungeon (not counting events, there is one worth 500 gold alone).
Which can buy you 1-3 level ups at level 1.
With 3-4 quest run, you can level up a single level 10 character (which is WAY ahead the game difficulty) or buy a top tier item (or, of course, several minor items are almost all the skills).
Seems fair to me.
I find appropriate you are broken after you buy a top tier item, or level up some characters. (Btw the need for gold in leveling up come from the boardgame).
On the contrary, imho XP are WAY too generous.
Cap in WHQ1 was 8 with Averland, 6 without it, and it required way more hours to reach. (Not really fair to compare a game with 1 years of expansions to a game out since not even a week, but you get the point).
I think being able to afford something super cool in 2-3 dungeons is perfectly fair...how would change that?
Game is already easy as it is...if you are given more gold too to buy everything in the shops...
I think that now that the base is set, a lot of things can be added...many were mentioned as possibile for future plans, or I personally suggested them (things like outdoor tilesets, ambushes, traps, escort missions, etc...)
Potential is imho huge.
Just my 2 cents...again I’m curious...how much gold would you think ‘fair’ for each dungeon?
