Finisher is just so obvious out of the stun and people on this forum have already mentioned about the issues of melee attack out of Cloud Walker, not sure why you needed to give people a 'hint' of doing something so obvious. You think you are the only one who knows this common thing?
However, I can tell you as I have been testing Wukong, both in simulacrum and soloing many sorties that are not supposed to be Wukong-friendly since the rework, it is definitely not 100% chance to land a finisher every time as you claimed. It depends on how you position yourself for executing the finisher, and the erratic movement of Cloud Walker sometimes hinders the precision of the positioning. In fact, you would have known what melee weapons and what stance that truly gave the freedom and 100% chance of executing the (stealth) finisher under the old Defy without the need to cloak yourself, especially soloing tons of high level mobs, if you were really a Wukong veteran.
I have over 3k (non-steam) hours in this game, nearly 11% usage of Wukong on my record. You claimed the reworked Defy is "undoubtedly better to the old defy where you were more focused on the energy meter than the game"? From such a claim, I can already see that you did not have enough experience with Wukong, let alone an optimal build for using Wukong in the past. I for one did not need to be "more focused on the energy meter than the game", you were clearly struggling for maintaining the energy instead of busy destroying the mobs like a badass by using a range of powerful weapons under the old Defy.
By the way, spin is just a word, of course Wukong is swinging his staff, I certainly did not mean it is something like spinning like Revenant or spin to win, that kind of thing.
