Server merges bring some changes. And ofc with changes some people get more nervous.
Me for example. I got a little more whiny and/or grumpy when i saw the initial anarchy and zergy rides. But now things get slowly back to normal and calm down.
The changes new people bring are nice and funny. I remember when Tyr ru**ers :P got merged. They bringed the jokes the fun and strange language in general. Raven's bringed the rides and little more anarchy, but hey it is game ment to be fun.
Do not take things so seriously after all.
