To the trolls that are telling me to shut up and go away; try putting some useful suggestions in as well rather than troll.
We did, and thus we got this current system. We argued your points there as well, had this same discussion, and all came to the conclusion we're trying to explain to you.
Every possibily discussed involving (1) dropping a group's aggro and (2) staying within the zone (by "refresh" mechanic, port to in-zone succor location, or other option you haven't mentioned) has been shown to vastly simplify many exploits, encourage griefing, and trivialize pulls/encounters. Note that this list of bad aftereffects is far from complete; I only included things that I feel would be obvious to any raider or staffer.
Now, I was with you until you said stuff bothersome enough to evoke my response. So, in respect to the assumed intelligence I saw in your previous posts, here is a more detailed explanation of why I hated your 4th post in this thread. I wouldn't bother explaining myself to someone truly stupid.
(1) Lesser Succor does not, in fact, work in a way that will cause a huge train of unpulled mobs, and anyone who trained you cannot attribute any part of the size of their train to succoring and getting extra adds from chasing mobs. Claiming that it does so based on a mere assumption from limited data is imprudent, but then you based your argument almost solely on this assumption and were bothered when we dismissed it. Also, not a single person in this thread would abide that druid doing as you hypothesized, even unintentionally. Your attack was petty and unjust, and I called you on it.
(2) As I stated earlier this post, your suggestion was considered (quite heatedly and carefully, I might add), and a decision reached. As you provided no more data useful toward reaching a new conclusion, Tao's response of "fine as it is now" is perfectly warranted and rightfully closes the matter until new data should show otherwise. If you honestly believed in the relevance of that last line, you would never have thought to post it. Mocking people, including the extremely rule-abiding Tao, for misuse of the forum can only be seen as childish and petulant. Your attack was petty and unjust, and I called you on it.
Also, don't bother playing innocent. You started this downhill intentionally, and you look really stupid for it. Man up and fix it.
