The purpose of WBL is for the DM to adjudicate relative party wealth compared to the CR of whatever you are fighting. (i.e. to make sure you have the appropriate gear to face whatever it is you are combating)
It isn't for the players to add up their gold and compare it to the chart an beat the DM with a mallet because they don't have enough cash.
Is your group having too hard of a time overcoming your foes?
If no, your WBL is fine.
If yes, is everyone having fun anyway?
If yes, then everything is fine.
If No, then you and the group need to chat with the DM to see about getting everyone on the same page.
How WBL functions with crafters is a very hotly debated topic. Whether it should net you more than your WBL or whether it should just let you turn your cash into the item you want is not something people tend to agree on- so you may also need to find out your DM's particular stance on that issue.
Yes and No, some enemies we struggle with and some other we dont.
One of the reasons I put out this query was due to the fact i am playing an oriental styled kensei and i picked up crafting for wakazashi because he said these would be beyond rare. So because my character uses no armor and has been making my own weapon, the rest of the gear drops have had little to no effect on my character compared to other individuals.
I was curious about the gold expectation due to group diversity and individuals strength vs weakness.
Also bonus to having crafting as it affects my party as well as my character.
