Epic actions, rescue missions, sacrifice, loyality and fun with all of that.
I remember all those cool actions, for example in unknown passage when last gate opened, everyone ran toward elevator but one person got surrounded and died, and he was like "Go! Leave me, run for your life's!" and we were like "No! Noone left behind!" and we charged to get back to him and bring him back to elevator alive, or sometimes it was just me and i run, and revived my friend but sometimes i died and he was like "No, why did you do that? You died" and he started fighting back to me and i was like "No, run and live on, it was my choice". And they have left on the elevator to sanctuary.
Those were fun times. And now they are gone. Today its rev spam. Died? Pah auto rev. Died again? Bah, spark of life, bam spark of life. So empty and dull.
I feel your ways. I remember my first time diving into candlestick keep. I was scared like the little noob I was. My entire team was down, telling me to get to the elevator. Being the heroic moron I was (reason for my name), I charged through the grimalkats, rescuing the 3*-4* leader, and revived the group. We fought our way through the horrendous ruined castle and reached the elevator just in time. I will miss the times of bravery and sacrifice.
