I already did it back then, work plus college. I had no issue, we even had people who only logged in for a few hours per week, when they logged on they did come and camp with us. Of course we gave gear to people who was on a lot but it was unfair for people who been there for a while to NOT get anything, so they all ended up getting things they wanted. It was all about having a great community in the linkshell you was in and people you played with. My friend is my FC leader and believe it or not, but he cleared all savages and he works 6-10 hours a day plus 3 hours at the gym 5 times a week. You don't need to be on 24-7 to do savage in this game, it's about devoting time for maybe 3 hours a day 3-4 times a week and know how to play. Many can't do that because they aren't learning fast, this isn't about a player playing more or less. You have people playing more than me and him and still can't do things.
I get what you are saying tho, but it's kinda untrue when some people do say they don't have time to raid when they actually spend more time than MC raiders in game. It's all about how you want to present yourself in the game too.
