For some time this expansion, monks have been a bottom of the barrel class on average for single target fights. On a lot of the high end performers a lot of them have high numbers compared to normal because of being able to take advantage of something like grief torch procs, but that still leaves the base class in a bad state.
A lot of the monks design for windwalker is based around expending a lot of points around touch of death; however, when it comes to single target fights, those talent points are of waste and there are not really any alternatives to those.
I think something that could be useful for monks, is that on either the monk tree, or the windwalker tree, to give these same touch of death talents an alternative selection. To what should be the alternative(s), I am unsure, but I do have some suggestions.
One suggestion could be that the alternative gives an overall damage boost, something to the effect of 3%. If I look at a fight like Terros, which is purely single target, touch of death did roughly ~0.5% of total overall damage in a kill of a relatively short time (4.5mins). If a monk was able to select otherwise a 3% overall damage boost, effectively that would make single target output increased overall and a more viable option and the monk still has the baseline ability to use, but not having to spend talents into it for minimal to no effective increase.
Another suggestion I have as an alternative would be to give the monks something like an execute phase as an alternative option. If the mob or nearby mobs are below a certain threshold, you output an additional % damage increase while hitting said mobs.
The thing about touch of death is how it works. You effectively have to use a GCD or an auto-attack for the game to actively check the target’s HP% threshold for the game to recognize that touch of death is now available. If you are on encounters where the adds spawned are of low hp pool thresholds and the monk is not able to touch of death said adds due to them being blown up, the monk is effectively losing overall output and is wasting several talent selections.
The numbers I am putting in here as an increase are purely subjective. I am just using them for more of example purpose of the idea, not that those should be the numbers; however, I do think with the current state of windwalker monk in raid, there could be some improvements made. Effectively giving alternatives does not weaken the state of the class and can improve the class where it is lacking.
