... I think attempting to make an argument when you haven't read the particular thread at all is a very.. Silly thing to do.
You misread my post, in part.
Second, I do not understand your argument of Specializations can't stack, Focus Items can = Focus Items ARE JUST BETTER! First and foremost, the box you are referring to on page 249 stats specifically that the only real instance that a Specialization can possibly be potentially stacked, is by some form of overlapping Thaumaturgy. And if you attempted to follow the box, to the description of Focus Items, or at least read the description of Focus Items it to its end, you'd know this...
I meant Focus Items SLOTS can stack. 2 Refresh can get you a +4 focus. Best they can do with specializations is get you +2, +1, +1, +1. So you can get a lot of power in an element or whatever via Focus Item slots.
Another thing is your example of +3, +3, +2, +1 isn't possible. It does not follow the pyramidal archetype that you mentioned earlier. The best you could manage is a +3, +2, +2, +1, +1. In order to have your example, you'd require to have an additional 2 elements, one at +2, the other at +1. (But as a note, this Pyramidal shape includes all of the specializations put into Evocation and/or Thaumaturgy. You could have a power bonus of +3, +3, but only if you also had some form of +2, +2, +1 +1 in control.)
Yeah, I had it at +4, +3, +2, +1, but then realized it isn't possible to get that (sums to an even number), so I reduce the 4, which made it invalid. Let's see, trying to specialize as narrowly as possible with refinement, you'd go...
+1 (0)
+2, +1 (1)
+2, +1, +1, +1 (2)
+3, +2, +1, +1 (3)
+3, +2, +2, +1, +1 (4)
+4, +3, +2, +1, +1 (5) (put 2 into one of the +2's)
Note that for the same number refresh, you get just as many points with Focus Items, but you can spend them however you wish.
Edit: Hmm, if you have one element that's offensive and another defensive, that frees up 4 slots (+2, +1, +1) for the defensive element. Saving you just 1 point while making it so that you need a focus.
HOWEVER
And yes, you could just to put 1 Refresh into Specialization, then 2 into Focus items for your example, but the +5, +4 would ONLY be good for either offence or defense, which was the very START of my argument, and beginning this thread. A Specialization either goes into Control of an Element, or the Power of an Element. A Focus Item is further divided into Control Offensive, Control Defensive, Power Offensive, Control Offensive. AND, in order to equal a Specialization in its complete, and rounded bonus of either to Control or Power, you need to double up on the respected Element.
I somehow have missed this fact reading the rules, and so I didn't grok that part of your argument. Wow, that DOES seem to suck as best I can determine.
Edit2: Let's expand the tree I made above, we'll pretend you just do evocation Evocation...note max improvement is bound by a slowly rising curve (logarithmic, looks like)
+1 (0)
+2, +1 (1)
+2, +1, +1, +1 (2)
+3, +2, +1, +1 (3)
+3, +2, +2, +1, +1 (4)
+4, +3, +2, +1, +1 (5) (put 2 into one of the +2's)
+4, +3, +2, +2, +1, +1 (6)
+4, +3, +2, +2, +1, +1, +1, +1 (8, must take a 4th element with a refinement, then specialize)
+4, +3, +3, +2, +2, +1, +1, +1 (9)
+4, +3, +3, +2, +2, +2, +1, +1, +1 (10)
+4, +4, +3, +3, +2, +2, +1, +1, +1 (11)
At this point, you could have a +5 control, +5 disc offense stuff, and +5 c/d defense stuff, and still have 2 foci left over. So it does get the point where Foci are better if you are focused, just takes a while. Specialization definitely gives you a broader base, however.
