I'm not going to read this but I am going to say that ninja and red wizards have been given a strength boost in the past before, that every class needs 2+ wayfayer equipment if they want to carry what they want/need, and the fact that ninja are faster means they will consume more stamina as a result.

There's an obvious pro and an annoying con with having higher speed, it's there for a reason. Usually in any game, if you have the option to eliminate any weakness with better equipment that doesn't curse you in any way (other than costing you more gold), it's not really that bad a con at all.

You already said you're not that good at the game, so learn what everyone else does and shaddup.

A good player knows how to play his class. An elitist knows how to play everyone else's class.
