Here's an idea that this forum is not going to like, probably, but something I was thinking about: you can get extra professions available for 10$ each, or a bundle for all of them for like 50-60$. And maybe a deluxe option to have that enabled on all your chars for even more money.
Yea, yea, I know what's you're thinking. Subscription game, you can have alts with other professions etc. But for convenience sake, I might consider buying something like this. I want to play alts for the fun stuff, not for farming/making money. And it's not pay to win, as the small bonuses to player power from professions were removed like 3 expansions ago. The idea of always be available to gather that rare herb/ore, no matter what char you play on, is really cool to me. Same for having the toolkit to craft whatever you want on 1 (or every) character.
