Like most people on this post, I'm a long time player and extremely frustrated.
Server stability and reduction of lag should be the #1 priority of the developers at this point.
No new content, no new DLC or events. Just fix current bugs, optimize current maps and focus on giving us adequate gameplay. This is what your customers and player base want most. Most of the tickets made for lost items or dinos are directly related to server stability. If you wish to retain a player base, then focus on the issues that are causing people to leave the game.
