Personally I don’t really mind that fish traps have gone from being passive to an active thing, I have always found it weird that such a useful resource basically was free 
I started on Siptah on official pve server some weeks ago, until then I just messed a bit with it on singleplayer, I got to level 60 in 3-4 days without rushing the levelling and I mainly used coal as fuel, I still do so I have a decent amount of oil saved up(almost a full chest)
I don’t really know how hard it would be if I had to start a fresh character right now, but I think with some balancing and finding new ways to resource gathering and how I spend them 
Some things have gotten a bit harder(grinding) while others have become a lot easier/faster, maybe the biggest problem is that we have gotten used to how easy oil and ichor was so that we never really explored different ways of getting them, and maybe we just have gotten used to having a huge closet full of epic armors, I most definitely have been guilty of this in the past 
So many changes have come and are on the way to the game, and with the economy update I am not that worried, I will adapt and wait for balances where needed 
However there is one place that seems to have been forgotten and left a bit behind, and that is the max amount of feat. points you can get from levelling, over time the amount of feat points have increased because of new things to unlock and also an increase of point cost for old stuff, yes the cost have gone up for some things, I recently discovered this by loading an old save where I had almost 100 negative feat points left, but this is for a different discussion in a new thread I might take up at some point, and I’ll do my best not to take a Skull approach 
Have fun and enjoy the game, also be aware of sneaky turtles and treacherous rabbits, they may look innocent, but I suspect that they are up to something and god help us if they team up against us
