When Edmund Hilary was asked why he climbed Mount Everest he purportedly replied "because it was there." I often think of this story while playing wow and questioning why bother with some of the content.
Mage Tower is one of the odder challenges in wow, not only because it is difficult but because it is exclusively solo content, time gated, and currency gated (per attempt anyway.)
At first I thought why bother? But with each attempt, especially on my alts, I was getting better at the game on a way that heroics or even overgeared Mythics can't offer and punishing Mythics (higher keys or bad pugs) can't offer for a toon I'm still trying to improve at.
Curious what other people think but I wish these challenges were not time gated. I don't care about achieves or transmogs. I want this kind of hard proving ground where I can home my skills. I want to take my rest shammy I haven't touched since Cata and practice. Don't really care if it's going to cost repair bills and what not.
Tldr - mage tower makes me better. Could make the community better players. Would love a practice or proving ground system.
