So you mean all should roll on these good community servers and have a good time? Just forget the chars leveled up to max on low pop servers?
There is nothing wrong with cross realm systems. Faster queues and more variation in warzones is a win for everyone. Can't see how an LFG tool is bad either, maybe it's actually possible to get a group up fast instead of wasting ages to make one.
Maybe you should try to play on some low pop servers and see how awesome it is. From my perspective it looks like you just can't tolerate to get mixed up with people from other servers. Well maybe your "perfect" paradise server won't be the same, but one thing is for sure, it will make the experience a lot better for many others.
