Last I checked, it was like 116 days for me. You'd think "Wow, I played a lot" but then you remember and go "Wow, I sat in a queue a lot" lol
It should be much higher, considering I started with 2.0, but the staleness of updates (same 1-2 dungeons for 3-4 months, sometimes more if you don't need the CT gear) makes me take breaks lol
