Mid issue 4, is correct. It went like this,
In PVE, huge -acc applied to travel powers. There was never a clear answer why, there were short quips about jousting, where a player could move so quickly by a MOB that it prevented retaliation to an alpha strike. When pressed with clear explanations that jousting in PVE may happen, it was such a horribly inefficient or tactically sound way to defeat MOBs that it was really a non-issue.
PVP was in development early. PVP landed in issue 4. Blasters straight ganked everyone by superspeeding while firing.
Travel powers were suppressed on any power that affected a MOB/player. Things live invinc would cause suppression. It was comical. Suppression was tweaked. The feedback was horrendously negative in PVE terms, continuing to demonstrate that kiting was a non-issue, and a bad excuse for suppression.
It was possible to continue to move quickly by 6 slotting things like hover.
The boards filled with continual feedback about how it was a bad PVE mechanic. This was in direct contradiction with Mr. J.E.'s "The Vision™"
Issue 5 brought ED. No little blue pill 🔵.
Ed and suppression reigned supreme.
The Vision "left" for "greener pastures" which resulted in said greener pastures becoming a largely defunct beta released clone; then left that too.
Meanwhile, sad 🐼 and the debate on exactly what was the catalyst for suppression continues, but rest assured, it was never sufficiently answered clearly, because The Vision was not great at that particular skill, at that time.
I would bet the family pig it was a combination of pvp and pve (primarily pvp, because the initial vision was to make them homogeneous mechanically), but only because it was The Vision's personal belief that it was necessary, as no actual evidence supported it.
