Maybe someone with enough motivation and investment in Wu Kong will start gathering stats to check the miss ratio.
Sure, it’s worth raising the possibility. If it doesn’t gain support it could mean that others with Wu Kong aren’t actually observing the same, in which case it may be possible that it’s observer’s bias. Or it could mean that you are sufficiently observant and/or sufficiently versed with the historical performance of the character that you could be one of the first to notice the trend.
Either way, the only way to concretely support the viewpoint or take the conversation forward in any meaningful way is for someone to start counting. Until then it’s really just idle chitchat.
Am I going to do it? Nah. I haven’t noticed a sufficiently large degradation in my Wu Kong Performance or my average Titan scores (I always use Wu Kong against Titans) to feel it’s worth my time to gather the stats. But if someone is sufficiently interested and wants to gain the attention of the community and/or developers to address the possibility, then supporting the claim with stats is the only real way to go.
