I found that prior to lvl 18 you will need to strafe, otherwise the distance is very hard to judge and you will get hit faily often.
Once you hit 18 and get the new song you dont really need to strafe, unless your going try hard and trying to hit with both the lvl 18 and lvl 2 song.
As for the 4 mob limit;
Based on the patch note date that mentions the fix:
