When should someone go to CWK now?

You don't need to collect any items for the map, do you? All you do is click Jack a lot.

And you don't strictly need 2800 HP. I got a guildie of mine to exterminate all the Elderwraiths, lol.

I believe you need 10 Stormbreaker badges to get the jumpquest bypass, and 4 typhon feathers to get the Key (forget the actual name).

Generally having all 3 items is worth while, the key does nothing yet but I'd rather be prepared.
