Given how you feel about it and the general low standard, walk away. Life's too short.
I did the same earlier this year, not because the standard was low, it was actually very good but other reasons were preventing us from progressing. I had realised this right from the start but kept at it, hoping the situation would improve. It didn't and was never likely to, so I did what I should have done a year earlier and left.
Had a break from playing for a few weeks and then did some depps and started the search for another band.
Someone actually found me a few weeks later.
Like someone else mentioned, we are a rare breed.
I cam remember that I did find it frustrating with Join my band and other sites, there are an awful lot of bedroom rockers and also middle aged blokes with all the gear, who want to kick up a din once a week every week for ever and ever but not actually gig, Also the band that have got the EP recorded, just waiting for George Martin to find a gap in his diary to mix it down for them.and blah blah ..............but there are some decent ones out there and one of them will need you
Good luck with it whatever you decide.
