Until I recall the nonsense you've spouted before, maybe...
As for your classification for offensive Vs defensive - fine if it works in your head, but not for me.
Take a pre-cast haste as an example - For you, precast=defensive, compared to "offensive" healing amp?
For me, something that helps me hit stuff faster, increasing DPS or other harm to my opponent, is what I tend to call offensive (e.g. a pre-cast haste), Vs, say, something defensive that instead helps keep me alive by someone having to hit me a bit more to kill me to get my red-bar down (say from getting more HP from a heal by virtue of having some HA so my red-bar is that bit higher).
hurts thier red-bar = offensive
helps my red-bar = defensive
and a few things can do both (Yay!)
As the meerkats on TV ads here say: SIMPLES!
Maybe just my lack of experience, but I've yet to kill a mob using HA alone - even a kobold - take it you've had more luck?
I think your flawed definition there may in-turn have resulted in your flawed initial list, and the resulting neccesity to come back on and explain your logic at length now, and maybe even to feel you ought to add in that "experience" quote too? (LOL!)
Trouble is now you've explained it, it still doesnt make a whole load of sense.
But then - waddiaino - I'm jus a dum barb wot likes hitin fings til dey stop movin no moar, den mebbe's agen, jus coz (not wi ma heelin amp do)...
