Listen outside of Small Pop Servers, it's not about the server but the people. Now those High Pop Servers aren't better per se they just have a larger pool of raiders. This doesn't mean you can just waltz in and get stuff done. The larger the pool means more competition you have to compete with to get a raid spot. You need to find 7 people who match your mentality and skill level otherwise no matter where you go you will have a time of it.
