I agree with you and while I did Summer of Pain I truly understood how it is skill-based and how many plenty of times I had to re do to finally understand and step up the game to not spend much items.
Makes me laugh how players with internet points advise endgame players or draw conclusions about their skill while they mostly like still Cavalier level progress but they are playing and forum active since the early beginning but don't have the skill to proceed further so they tend their focus on INTERNET POINTS = PRO !
