Firstly can I say thanks to @LadyGeek and @Trollypolly for your replies. Haven’t been able to do so since I’ve been away for some time.
LadyGeek your response cleared up everything for me.
Trollypolly I have some thoughts on your tables, which you don’t have to listen to if you don’t want to Don’t get me wrong it’s great that you did the testing, but if you invert your figures to format it in the way it is shown in the topmost table in the thread (i.e. AP/%dam), it comes out pretty much the same anyway, which leads to two points I will raise. The first of which is that it doesn’t make any sense to me for the game developers to code with non-round numbers. Why use 1.247 instead of 1.25 for a huge bonus on defence? Secondly since these are empirical figures, they’ll be based on the two significant figure AP counter you see during duels. This means you shouldn’t really be listing your results to any more than 2sf also.
Having said this it was a useful video, as I noticed a discrepancy in the very large bonus to ap on defence and having conducted my own tests can confirm my results agree with your figures, equating to a 1.1 rather than 1.15 multiplier. If I feel like doing more tests I will look into whether your (for example) 1.247 is more accurate than the 1.25 multiplier, although I doubt it very much.
I am of course only referring to the AP when defending part of your video, this was the only part I watched (sorry ) as that was the area for which my understanding was lacking.
So overall, thanks and those are my thoughts!
