If you had read the entire discussion like you claim I should, you would see I have been posting repeatedly thru this discussion. What people are simply saying is that this idea of the OP to create a raid style start to BG's would not work.
A. Gear Requirements: Have yet to hear how forcing a gear requirement for a lvl 85 bg but not having one for the 80-84 bracket makes any sense at all. Also what is the magical gear requirement, Twilight Highlands lvl? What about the people that leveled thru BG's? There is no progressive gear between 80 and 85. Increase the ilvl of lvl 80 pvp gear for those that didn't go thru PVE or does everyone now have to do PVE to play BG's?
B. Role Selection: You would have DPS select healer role without actually being the healer. This already happens in raids and dungeons, if this is news to anyone, they must not have been on wow for long.
C. Queue times: Just because some high pop battlegroups and servers have low queue, doesn't mean all servers share that. Many of us already are 7 minute queue's we don't want 2-3 more minutes just to appease someone that thinks you can only win with having 2 healers.
D. You can win without having healers! This whole discussion is moot because if you are good players you can win without healers, maybe is a learn to play issue rather than a "I lost it's because they had more healers, they need to change everything for me" excuse. Hell you can even win with 1 massively undergeared healer.
On another note, it is your way of typing that at times makes it hard to understand what you mean. So I apologize for thinking you meant length of the BG's themselves rather than them being in WoW for a long time.
