i just played huakke manor with a friend ( healer ) who has swiftcast pretty early

we made it to the final boss ( lady something i dont remember )

and other DPS died about 3 times yet my friend was raising her with swiftcast

after we won the fight he started saying who come you raise super fast?

my friend said i got swiftcast skill

then the DPS ranted saying its one of the broken skills then

say what? broken huh? you died 2 times and you say broken?

all ppl gets happy for winning and you rant because of healer more than just useful?
