Lets say you work a full time job and start work at 8-9 AM and finish at 4-5 PM. Assuming you're a raider, that means you have 2ish hours until your raid starts at 7 or 8, depending on your guild. That 2 hours can be spent grinding mats for raids or leveling an alt. An adult has the ability to play just as much as a kid does... they just need to budget their time. Instead of going downtown w/ the bros, you're sitting at your PC raiding w/ 24 others. I only made that sacrifice when I was in top 50 guilds US. Prior to getting in those guilds, i'd flake instantly as soon as i knew a few friends had something planned. Every excuse from laggy too cat on fire was used, but when I was in the top end guilds, i'd cancel on my friends and sit at my PC for 5 hours 4 times a week. I was working 45-50 hours a week too when I was in top end guilds, I just had to take a hit to my social life, but it was worth it in my eyes.
