Before I begin I'll have to say this. The majority, if not all of the loot doesn't interest me.
Because blessed with the timezone that I am in, spawns are very often low.
General lack of interest to dungeon due to that, and seeing no point in it as well, do take away from some of the fun.
But I digress, I don't think it's about how much of your resources you'll toss at something that won't yield any worthwhile reward.
The issue I see foremost is that it segregates newer players even more from people who have played and know
PotM's systems well enough. From my own experience of talking to and with new players, especially those who haven't even played NWN before,
is that they're often frustrated. They don't have anything, get nowhere and their best stop is to go straight from Vallaki to the Mist Camp.
That is, if they don't find it deserted. And how does the loot containers' (very, very late) fix connect to that?
Before, people could reliably get enough money to buy that random bit and bob they may need. This is only my estimate, but the change may
make the 'Rich richer and the poor poorer', as the saying goes.
tl;dr - This will only hurt the noobs, anyone else will probably live with it and notice no big change.
