So it seems that many people think that you should/have to go with a single class to be at par. For many casters this may be true but for any build concept that is not a caster I say why not multiclass. I frequently do one to two level dips in many classes to make a solid build of any type and believe that multiclassing is the way to go.
What brought this up with my most recent build concept. It is a trip build that will have monk/fighter/magus/barbarian/alchemist by the end of the build. This may seem like a lot of classes to many with low synergy and missing out on all of the strong later game abilities for each class but I think putting a couple level of each together can come up with a stronger build than any solo class.
I am wondering what your thoughts are on this subject and why?
