The top crafters have already given their input in another thread, asking for more incent to craft by re-introducing wisp system etc. But it was ignored for the most part or simply not acknowledged. We're at a patch at which too many things have been damaged past the point of repair. And even if you somehow managed to bring back alive a lot of the things that have died on the way to 4.5, you'd put anyone who starts here now, at great disadvantage.
For the gold-generating methods: Fishing has had an increase but is still not on par with larency. Tradepacks have always been shit if you ask me, unless you dedicate 5hours a day prepping and running packs across the whole playable area in this game (kark packs overseas etc.). I know many think of packrunning completely different than me, but I never saw much incent to do them unless I was bored of my usual ways to earn gold and needed some variety.
Crafting is pretty bad in every profession and the profit margins are low for how much time and labor it takes. Larency is very powerful and in my opinion the best by far.
There's a few ways to making gold that don't inject it right into the game, e.g. by grinding certain items or flipping things. But those are either extremely grindy or there is not big enough of a market to enjoy flipping reliably. Most of the geared players I know simply put hundreds worth of real money into the game each month. I can't give you the name of a single person that has joined us past 4.0 and has geared himself into the rankings as an entirely f2p player.
