To Vladimus:
I read about the "Just in Time" Cure for DS, but seems unable to pull it off, (i usually start my Cure II cast around 55~60%), best I seen is tank HP go down, then immediately go back up due to my heal, and it's still affected by the Infirmity debuff =\.
2nd tip I am aware of it as well, thanks!!

To Fyreus:
I would love to do so, but I am already averaging 23 FPS with my laptop, I think if I start recording, the FPS will be hit so bad that it'll be unplayable, I'll surely take your advice if I manage to get a better rig in the future.
