This is the video, showing how easy it is to do well if you have mobility enhance, stealth enhance and energy transfer fully upgraded.

However, I do not believe that it is the combo that is unbalanced, it's just that it is unfair for players that have no upgraded modules yet and can not compete. I assume that once you fully upgrade cloak tracker, it would be a viable counter to stealth enhance and energy transfer. However people who are new to the game have no chance against someone who has the 3 modules fully upgraded. My k/d jumped from 1.5 to 1.9 since the upgrade in the 3 modules I mentioned above. I think that matchmaking needs a tuning; the game should do more to keep low level players with low level players.
