So, something we've been discussing today that plays into this conversation is this: There's no reason not to start as a warrior even if you plan to be primarily a skirmisher or elementalist. Grind up 10 strength and get 1500 prowess to buy the 4 strength boosters, then get a set of plate. At this point you can grind up your basic attacks (staffbolt for elementalist or archery for skirmisher) while wearing plate. This will level up those skills as well as increase the dependent stat, so that when you're done leveling them to 100 you can switch to your preferred profession and already have really good stats.
