Yo, for anyone interested in what the Soul Level meta is, I warn you that Soul Level is only relevant in the arenas. Outside of that, soul memory determines matching. As for the actual "meta", most people agree on somewhere between 150-200. Personally, I just aim for 200, considering 150 is only good for RoBFlynn builds, which I despise with a passion. Really though, you can stop leveling whenever you feel like it, I just ask you don't become a level 387 havelmonster.
