One frustration I experience is that I can't be of much help to newer vapers anymore, as my preferred setup isn't a new shiny development. One can't help troubleshoot stuff that they've never used. vaping has become less hobby, more long term relationship. ECF and meets are still fun, just not as exciting once you jump off the upgrade train.
I feel the same
Newbs keep asking what battery do I need for "this" coil, and I keep thinking why not learn what coil you can use with the battery you already have?
