Funny how the grinch peacock and evergreen double almost perfectly counter each other.
Grinch peacock converts buffs to debuffs while evergreen double extends buffs.
To be honest, the SA1 thorns is pretty scary too, forcing enemies to only use elemental advantage against her since curse would be also removed by SA1.
I think I saw one in dailies with extends buffs by 5s so the SA2 is probably 3/4/5s . 5s is pretty crazy for a lot of characters, especially Jawbreaker, DjinnFrizz, and any grudge MA (but unfortunately all very very hard countered by Grinch Peacock - mean one, since the 5s extended buff is simply converted to an 5s extended random debuff)
