Nobody is making you do long elite runs. You don't have to do the last elite map if you dont like it. It's there to be a challenge for players, who are really up for it.

Jarl you can run easily in 2-3 minutes, same goes for Reef when you're farming it. So you can still get elite items, without having to play for hours and hours.

Yes, if you wanna beat the last map, you'll have to take your time, but if you're just a casual player, you can still enjoy quick elite runs
