-The cape is just a utility cape, just like it is in osrs, people dont max to get the max cape to quote somebody, " runescape is about setting goals and then achieving them " thats the whole point, maxing dosent need to have some form of crazy reward for doing it.
-You make plenty of money whilst skilling, sure its not as much as camping raids all day, but it shouldnt be the best money maker in the game either, considering how chill/afk it is, its very respectable money, and you can easily make like 1-2mill maxing.
-you dont *need* xp scrolls, i know somebody who maxed never using them, you are spending 45k to save an hour of skilling. for me personally i just use it to train my least favorite skill and for nothing else
the only point i agree with is that some of the achievements for skilling can be a bit of a joke.
skilling is what it should be. a chill optional way of spending some time and making a bit of money whilst doing so. and then progressing towards leveling up the skill and making ur way to maxing. i feel like skilling accomplishes its goal relatively well.
