That's an interesting question you have there :) on a scale of 1 to 10, I would give it an 8.5
I can surely say that you are indeed missing out something awesome and that is a good thing actually as you will have the option of discovering all that for the first time. But if you have any friends who actually play it - the best way would be to get together with them and play a map or two and this way I guarantee that you will 100% love it.
