I've tried to explain it. I've said my views are based on my experience with the spell, and games I have seen. Yours is as well.
My position is that people should try the spell out, over a fair period of time and variety of situations, and see what conclusion they draw from that experience. Yours seems to be "it's objectively broken, and people shouldn't bother trying it". And yet, you have two people here who have tried it and not found it broken. So, it's not objectively broken, just subjectively broken for some people.
You trying to persuade me that, my experience with the spell notwithstanding, theoretically it seems broke when placed in specific contexts on paper which really are (despite your protest to the contrary) meant FOR that kind of spell, isn't really addressing the issue I am getting it. I admitted long ago that the spell can be broken given the right circumstances. All I am saying is that, given the right circumstances, it is also perfectly fine, and that people should try it for themselves in a fair way before tossing it out of their games.
But instead of addressing the issue of why you and others think it should never even be tried in games, you guys seem to keep focusing on specific situations which I think you know full well in advance are tailor made to focus on a spell like that, at higher levels only, which are not typical builds or encounters for an average party in an average game. And then the protest comes as to why it's not tailor made for that, even though it's a spellcaster build with all melee-oriented feats and equipment.
I say let this issue drop already. If you have not gotten my point, and I have not gotten yours, by this long a period of time, then it probably won't happen. Reasonable minds can in fact differ on subjective issues, and often do. It doesn't make one of us absolutely wrong or right. There is a certain art to this game, and everyone's games are different. If you are looking for objective black and white answers in a question of art, you will look forever.
