Wonder if D2R is popular enough, if there will be a maxroll equivalent site for it. D2 was born in an era where internet isn’t what it is now. Be awesome if there was a centralized site with all the resources and a similar tool like d3planner (d2planner) perhaps? 
I’m pretty confident that MaxRoll will cover D2R. They already have a D:I section.
Why not just ask them?

It’s good to hide emails (for example with details tag) so you don’t subscribe them to spam after bots catch the email.
