So uhh. You should kill those mobs that are respawning fast. Because you will gain a lot of EXP quickly. I normally also add “and money/drops too” but that’s not especially true before level like 14. The constant respawn is greatly in the player’s benefit in so many ways, because killing mobs is better than most questing. Not wanting to deal with every mob you run across is a self-sacrificing way to play and you will be hurt in the long run this way.
Also. Watch your back if you don’t wanna be respawned on `~`
