To echo Al, yeps, level 30 is like another version of the game - experimenting with builds etc.
I proper enjoyed it, but I don’t “do” the PVP part of it and with each patch there are different metas.
I actually have a character (you can have 4 different ones) whom I’m grinding. Can’t remember what level they are at, but they defo not at level30! If you want to team up, as you’ll then grind quicker cos rewards are bigger cos you playing at higher level than your eqpt, shout.
