I chose this server as it allowes me to speak my native language. Despite of this i havent seen anything that would let me regret my decision. I like the 25x rate so it is possible to advance fast without completly dropping the leveling experience. The main drawback of Invictus is that there could be much more players around. The community is more Discord-driven than ingame, but it is possible to participate in events. If you are a german language player, give Invictus a try.
