I am in exactly the same position. I paid full price to play this game for fun in "solo" mode which was a Portal PvE server. I was able to do this for two weeks after launch and then this feature was removed. I tried to get a refund when the feature was removed but it was declined by Steam as I had played too many hours. I'm not fussed about XP or progression, I just want to have an enjoyable experience playing against bots at a more relaxed pace.
If the option to start a PvE server solo doesn't return then this will be the last BF game I'll play unfortunately. It's been very disappointing as a BF fan since 1942 and DC.
