Conceptually, LoL filled a hole. DotA was DotA, complicated, hard, lots of nuance. Some people wanted an even more complicated DotA. Heroes of Newerth filled that hole. Some people wanted a simpler DotA. LoL filled that hole.

I personally preferred HoN, but I can’t fault people for preferring LoL.

Yup it will. In fact well before the water boils the chlorine will have come out of solution.

Sorry I read "hopefully" as an imperative. At least in the US static home IPs are very rare so I generally assume some form of DDNS will be needed for any home hosting solution

Or just a dynamics dns service like duckdns. Point a CNAME at your duckdns name. Or better still, a cron running locally and updating cloudflare dns etc. Lots of better options for home hosting than hoping your ip stays static.
