The same I could ask to you. Combat/Raiding and the other stuff are that big of a deal? They don't affect housing at all.

Some people just like to fight and complete the end game as fast as they can.
But others just enjoy that while their favourite activity is not related to combat, like housing or crafting.

In my case I just care about DPS jobs, Housing and probably Triple Triad. Not everyone have the same preferences or goals or interests as you.
