I mean, obviously play what you want...but I would really be interested in how "invisibility is a crutch' is a legitimate statement. As a wukong main, how you use his W is arguably the most important factor to being a good wu and being a great wu. Stealth isn't a crutch, it is a monumental factor in your ability to outplay, outduel, and outtrade your opponents.

Warrior gives you 2400g in stats for the price of 1625g. Sated Devourer was more gold efficient yes, but it doesn't exist anymore, so arguing based on its stats is pointless.

All that being said, I play full AD assassin Wukong. I may end up with one tank item, generally being DMP. His AD ratios are some of the best in the game, which is why a full AD based build is really the most efficient way to play him. Which also means you have to know your limitations, you have to pick and choose your fights very carefully, and you have to have extremely proper execution of your combo and your ability to escape once you've completed your goal of assassinating key back line targets.

Now, all of that being said, you are bronze 2. There really isn't a 'nice' way to say this, but your knowledge of the game is arguably lackluster. Your choice of champions also indicated to me that you probably don't have the best gamesense, nor the best judgement of limitations. Which is why you like playing champions that have their own crutches, whether that be the fact that they relied on an item that was way too efficient, that allowed you to go in and do whatever you pleased simply because it allowed you to build extremely tanky, while retaining a large amount of damage. You really didn't have to 'think', you just went in and did your thing.

Now that you are forced to play more cautiously, to play more efficiently, and to calculate your decisions beyond 'go in' or 'don't go in', you've decided that everything else just isn't good enough.

Yes, some mindless faceroll champs lost the item that allowed them to play that style. Hopefully the buffs to razor help, but none of those champions are completely useless as you seem to think.

Then again, you've only played 30 ranked games, and a lot of aram/special queue games, with some normals mixed in. Sorry, this might seem egotistical, but I don't think you have the experience to bring proper arguments to the table.
