Starting June 28th, you will no longer be able to log in to a Curse account that was not merged with a Twitch account. If you have not yet merged your Curse account with a Twitch account, please do so here! Otherwise, your account and its content will be inaccessible.
But to answer your question, almost nobody has all of the runewords memorized, so when you get a two sockets staff going to that page and looking at the 1.10 and 1.11 page (ignoring 1.12 since those are all class specific), you can just use a page like mine. Another use case: Say I have 20 different runes, what runewords can I make/almost make? You can use this to find out.
