I agree it comes handy from time to time. You are always able to diverge from a standard guide (like the one I gave) and mixing things up such as 2/5 Aspect of the Hawks and 3/5 Endurance Training
Just an advice I can give you though, don't bother spending gold on respect while you are leveling a hunter, if you put a point or two somewhere you realised you don't need it ; it doesn't matter 99% of the time ! Keep your gold for the respect once level 60
