Just checking back in to give some data.

At level 86 with 60 dis 60 int and 30 charisma, I put all of 65 mana (straight prep no harnessed mana) into a calm on a moruryn and I couldnt get it to immobilize.

Is the immobilization effect gonna get worked on a little eventually? I dont wanna sound like I'm complaining but it still seems to be unrealistically hard to do.

P.S. I plan on getting my charisma up to around 40 or so eventaully but it'd really kinda suck if my higher stats (dis, int) were limited by the lowest stat (charisma) in the equation for WvW success. Rigby, can you lemme know if this is the case? Ex. if I had 100 int, 100 dis and only had 10 charisma, would this effectively make the value of my int and dis worth less overall in the WvW calculations because of the low value of my charisma? Or are the three stats independant contributions?

I can still command a passive opponent after they have become enraged. Edited log is below.

[Riverhaven West Wilds, North Meadow]
Singular trees dot the meadow as it climbs its way toward a dense forest to the north. The sound of running water rises from a steep creek bank to the south. You also see a dusk ogre, a dusk ogre, an arbelog who is lying down, and a dusk ogre.
