It is quite clear SE is willing to reach e-sport level, but today is quite difficult reach that level starting from ground zero. Unless SE takes consulting from experts on the field of PvP gaming, I'd expect still a very lot of trial and error before PvP reaches the minimum requirements for being e-sport grade.

First step is everyone be able to load and replay PvP matches (at least in tournaments). It is necessary for everyone to improve, and makes cheating more evident if done by anyone in the party.
