I'll concede that. Tectus is likely the worst fight for feral that I've encountered on the Heroic/Mythic level since I've been playing cat. Even a fight that is *good* for feral, feral is outshined by an incredible amount. Twin Ogrons was an example of a fight where feral was able to take advantage of high mobility and cross dot on them both and do well. Cross-dotting is 100% intended design for feral, but combat rogues do that fight better too. Why even have feral in the game at all if rogues and others can effortlessly outperform in every facet of the game. It is just debilitating for those who love to play that spec.
Feral outperformed Rogue throughout much of Highmaul, you just happened to pick a fight that feral is terrible at (tectus) and a fight that combat was exceptional at (Twin Ogron). If you were to compare feral on Kargath, The Butcher, or Ko'ragh we were far superior to rogues. I will concede that this is not the case in HFC, rogues are far too overpowered given the state of the rest of melee, but for highmaul it was not the case
