The problem is that extremely few people play dungeons/raids and dungeons require whole trinity which makes it even worse as certain role gets uber long queues so they quit too.
You just cant win with these dungeon DLC, its clear loss for ZOS.
"Just some stats from PS4 trophies.
4.5% of all ESO PS4 players have cleared all DC base game group dungeons, 4.4% for AD and EP group dungeons at least on normal.
2.6% have cleared Mazzatun and 2.4% have completed Cradle of Shadows at least on normal difficulty.
1.6% have completed Bloodroot Forge and the same number have completed Falkreath Hold on at least normal difficulty.
1.4% have cleared Scalecaller and the same number have cleared Fang Lair on at least normal difficulty.
0.7% have cleared March of Sacrifices on at least normal, and 0.6% have cleared MHK on at least normal difficulty.
When you start looking at the completion rates for both dungeons on veteran in each pack, you’re at 0.5% for Shadows of the Hist, 0.2% for Horns of the Reach and Dragon Bones, and 0.1% for Wolfhunter."
Numbers are numbers and show clear defeat of DLC dungeons and miniscule playerbase participation.
Really needs design based on reality, there are no tanks and few healers, because the rest of the game is designed for DPS...
If you wanna queue quickly, ask in zone chat for other people who are queueing too, group with them first, profit. Even if it's 2 DPS, it goes fast.
lol - no doubt!
soon there will be mechanics on the login screen.
*EDIT for this question. Does a group of 2 dps get pushed ahead of sinlge dps in que and get their tank and healer first?
