Those would act on our core spells, and not on a specific talents, and whence are not needed to be known prior to giving feedback on talents.
And that's what tiberria actually does, once you look behind all his numbers: Profusion is a bad mechanic, Cenarion Ward lost most of it's value with with the change to swiftmend, a talent not standing on it's own, but requiring (several) other talents is far from ideal, as it severely restricts choice.the fuck down for a second, and focus on the actual gameplay of the class.
Going by overall throughput, yes. Tuning individual mechanics on the other hand is not. Take Inner Peace for example. It's has two states: it provides an additional Tranq worth of healing, when the CD's align with encounter length, it provides zero benefit, whenever it doesn't. To keep class balance in line, overall throughput will have to be tuned for the first case (i.e. you get the additional tranq - but it does not exceed other classey by far doing to), which then neccesarily forces the other two talent options to provide similar amounts of healing to that of an tranquility.Tuning a spec is easy
And this is still by far the easiest "tuning" problem, because it is not affected by cross row balance: Flourish increases SotF's performance by up to ~70%, so either you tune SotF for pairing it up with Flourish (in which case it falls behind the entire T75 whenever you don't), or you don't (then it pulls ahead of the reminder of T75 whenever you do pair them). They did not manage balancing this for RaGr/SotF, yet they're now trying it for: Prosp/SotF/Germ/Flourish (basically that's a factor >= 10 to reju single/spot heal performance)
People tend to ignore the tuning early in beta, and then always are left wondering why some mechanics still underperform even after the tuning pass. The reason is usually quite similar to the above: the values to not underperform would fall outside of a "reasonable" (e.g. not to bursty) range (either indivudally, or when interacting with other mechanics)making a spec rewarding and fun is not.
