As someone who played P+ since before it was official TLC, but only on official servers... it's playable. Always was. There were issues after updates, but most were resolved. Anyone that played a lot of P+ understands that it is abandoned. Player base is too small and the negative associations others have with P+ will not go away because some little things get fixed. People don't want to spend 1/4-1/3 of their available playtime loading, don't want to be unable to play maps they payed for... and it's impossible to fix this without P+ going back to unofficial mod status and someone else taking it up as passion project, which is very unlikely. I don't want officials wiped where there is years of history and work, and at this point that is only thing I'm hopeful for.
