I noticed some people saying that a great way to level since 6.0 is by soloing dungeons that are about 3 levels below your own levels.
This has mainly been said about 85-90 but I've also seen some people talk about 80-85. I was wondering however at what level this becomes viable, or better yet at what level do we start getting the damage increase against lower level mobs.
It would make sense if this buff always works since it would be odd to not be able to kill lower level mobs easily as a level 60 for example however my warrior is 73 and I notice that my damage ( while being slightly increased due to gear ) is still basically the same on level 68 mobs as it was when I entered northrend.
Don't get me wrong I am not saying level 68 mobs are hard to kill as a 73 but the damage increase buff is clearly not present while as a level 90 I see an extreme increase in damage against even level 87 bosses which is only a 3 level difference compared to the 5 I have on my level 73.
So if anyone has any information on this matter it would be more than welcome.
Thanks in advance.
edit : Also I was thinking about this for a bit more, might it be so that this buff is only active when doing previous expansion stuff? Since on my level 90 the 87 bosses I was talking about were in Zul'Aman while my level 73 was trying to kill lower level mobs in his own current level expansion.
