I want ET's volume to be doubled, the whole map to shake, and the atmosphere to be split in half every time I use it, launching every nearby minion into the walls and blowing my target into the wall, stuck into it due to the sheer amount of force being applied by the physics engine causing it to clip through the foorls of the map and banishing them to darkness forever.
but I'll settle for the 'bam' on it currently.
In all seriousness though, If energy melee has one weakness, it's visual flair. From the pompoms to the general 'impact' of it's attacks. That's always been the major turn-off for me, combined with the performance. ET's new FX/sound is really nice, to me.
