That depends on how you play. Having a safe spot where the monsters can’t attack you but you can attack them can be a lifesaver if you draw too many towards you and need to retreat. On the opposite side, however, some players like to camp in spawn zones and simply blast away at the wyrms for no risk. As long as you’ve prepared your weapons and armor appropriately, a level 62 slayer should be more than enough to take on most wyrms unless something crazy happens. You shouldn’t need a safe spot if you don’t like using it, or maybe you want to use it because that’s the type of player you are. It’s an option, but it's up to you.
