I understand your point but the way you're portraying it is that you rely on certain buffs; for example agi and bless on your character's stat build.
These skills are called supportive for a reason. To support you, to boost what you already have and make you temporarily stronger.
If you incorporate these supportive skill in your main build then really you're asking to be a target cause as you said, it's easily dispelled.
I agree with the link but the buffs, not really.
