lb used to be good in 1.0 up to early 3.0, for most at least. Once people went over medium refine/thread level this event lost a lot of its value (same as mission dealer until recent box change). Ever since then, it was never that good as it used to be. If you need bp there are more efficient ways (and lb didnt offer pots on board), if you need ninja there are cheaper ways (direct buy) or alternative price but with more desirable side items (situational- lucky stars, great plates, current mission dealer, fireworks). LB is mediocre at best in its current state.
