Can we please redesign the entry system for dungeons?

I'm simply just tired of losing my 1 entry for KDNM (and finding a group on my realm Fraya itself seems to be few and far between, it's all KDHM) because half the group doesn't even know that if a giant message shows on the screen that the second boss targets you and you have to kite him into the adds.

Or melee dps dying 20 times on the first boss because they fail to dodge the boss' backflip.

Or die at last boss by standing in the water when having debuff.

Make it so I don't lose my entry if the last boss doesn't get killed through LFD matching, simple as that. It's really discouraging to even consider queueing up because there's a high change half the group has no clue what to do, even though you'd expect they understand the basics because of Kalivans challenge -_-'
