Dusted off my bear and was looking at some trait tree builds. I noticed that many dps builds take "serrated edge" in the red tree and "opposing presence" in the blue tree. My question is, why both since serrated edge makes your biting edge attack become a single target rather than an aoe attack, while opposing presence increases the aoe damage of biting edge. To me those counteract each other? The only benefit I can see is that if you put all 5 pts into opposing presence that you get a taunt and a cool-down. Just curious if I am missing something else or not seeing it correctly or if it is just more of a filler to get to lower tiers.
