but you can do the same stuff and repeat. Same locations, bad drops even with 500% mf.
That's why I do many different things instead of mfing all the time. Also, with shards it opened up the ability to mf basically anywhere now so you don't see the same stuff all the time.
But yes, Pvm is very monotonous most times, so you need to do other stuff like trading and pvp to break it up. If you burn yourself out on the same and runs over and over, you'll get bored fast.
And no, you don't always find garbage. You likely don't know all the stuff to look for. There are probably tons of items you're skipping that have some value that you aren't even picking up, but knowing those items comes from experience from trading and playing a lot.
