Interesting thread. I made a spear hurler from a Sohei (you can make anything out of a Sohei..). Many attacks, good move, can still wear armour if you cant invest in Wisdom, very good saves, good initiative, weapon training and flurry with whichever weapon you chose.
After level 6 dipping or continuing in other classes works well, such as Barbarian.
Off topic In Topic...It is strange to me, perhaps for not being from the American continent, the touchiness of certain words and allusions. The faster people are ok with terms such as "spear chucker" and do not associate it to old racial slurs, the faster the whole thing will be forgotten. Make a tabboo out of it, persecute it when it wasnt said as a racial insult, the more fire you're throwing at it and the more staying power those words will have. You're prisoners of your own words and your PR world.
