Thank you, Bewildered Zeratul. I'm loving all of the debates here and that's for which I was hoping. Please keep them coming, as I'm trying to finish my general guide as well. New ideas or thoughts would only enrich it.I'm following my own "train of thought" and gratually approaching yours. @Haydis the Fair If I abruptly jump into your "train of thought" and wear your shoes, I would not be able to think clearly because the thoughts would be foreign and repellent to mine.
As our trains of thoughts gets nearer and nearer to one another, however, I think we can merge, and simplify the subject as follows:
Is it true, that, after the golden spots, i.e. the 1st/2nd/3rd spots are done in x1.9 thread, the good old superb fantastic x1.9 degrades to the point of as bad as solo-leveling?
Or in the way how @klods hans put it, in short: 1.9 -- good; swap -- medium; solo-leveling entirely -- bad. (hereinafter the preferentiality order).
The preferentiality order applies to all 5 reward spots on a GB in the same way, and there is no differentiation between 1st/2nd/3rd spots on the one hand and 4th/5th spots on the other hand.
In my first write-up about To Swap, or to 1.9, that is the question ... , I described the finding of the "degrading" rates of FP Return for each position used in 1.9 calculation. And it is actually modeled after "the law of the Diminishing (marginal) Return" in the real world. Too often, the love for 1.9 is based on a "take it or leave it" point of view (meaning to level GBs exclusively via 1.9). You are right, for P4 and 5, 1.9 would not give you the fantastic rate of return as great as P1-3.
What I am proposing here is, if you are lucky enough to be in a Unicorn guild that has an honest and active swapping system. P4 and 5 (actually GBs before level 15 for some of their higher positions) could benefit from said "unicorn" swapping system more than via 1.9.
