Pro Player with the Longest Peak in Dota 2

Hey folks. On Gorgc's stream with Notail at one point they raised a very interesting question that I wanted to get a bit of a census check on. So I wanted to bring it here and see what names come up most consistently.

In your opinion, which professional Dota 2 player in it's history (say since TI1) has had the longest stint at a peak performance?

Criteria:

• Not necessarily who had the highest peak.
• Not necessarily who has been playing the longest
• Situations where people peak and valley, peak and valley would inherently be a disadvantage.
• Don't include Dota 1 or HoN years in consideration
• Factor in players retiring/taking long breaks and coming back as a an end to the stint

The concept behind the question is to understand which player has been able to maintain a high level of gameplay across time?

Post name and period/teams they were on when describing.
