You don't have to put in a lot of time each day to get good gear, just need to use your time wisely. If you want to goof around, just know that you are not going to lv your guy up as fast as you can. That is ok because you are playing the way you want. If you want to raid sooner, then you will have to "grind" a bit more often. Just remember, once you are done with the "grind" then this game start to slow down.
