Storm trance needs a nerf and you know it. Electro static mind does damage to anyone near the warlock whilst the super can actually do damage around corners and behind walls. Ionic blink keeps you mobile and extremely hard to hit. Of course using blink takes more super energy but I use transcendence which keeps it up for a long time. Right know I'd say stormtrance list the best roaming super for pvp and stormcallers even have a decent neutral game with thunderstrike.
