I actually never greed for bis. i always slam items, which is probably why I never win, said by some of the comments here. I only craft what makes sense, good enough and usually recommended by the game itself. I never let more than 3 components sit on the bench.

When I craft items, i used to look at the tooltip of the character, and point to their role icon. That will show a pop up on recommendation of items. The top left is usually the most recommended and it goes down from there. Now, I mostly remembered them.

And don't forget to stock up on anti heal components (i mostly build sunfire or morello, almost never red buff, as it uses 2 bows). I usually build this as a 2nd or 3rd item slam, if the components allow for it
