I suspect this too, I never leave dungeons and I’d say that I actually get Blackrock Caverns or Grim Batol more often than Deadmines.
Length and Complexity
Deadmines is by no means complex, multiple bosses? What are you on about every dungeon has multiple bosses and of course it takes longer than Stonecore or Vortex Pinnacle but it’s not as bad as some would make it out to be. Deadmines takes on average 30 minutes if you’re slow to clear, it can easily be done faster if the tank pulls more trash, the healer actually keeps up with it all and the DPS doing good AoE damage but at this point I think a fast Deadmines is ~20 minutes.
Also, the OP of Deadmines 80% of the time in random heroic queue (your first link) is just a flatout selfish player and so…
...I'll just repeat what I said in that thread here.
High Drop Rate in Queue
I honestly don’t see Deadmines that much more than other dungeons, or at the very least I don’t notice it as much as others here claim. I more notice getting more Grim Batols than anything, maybe it’s because I dislike Grim Batol but oh well… Still wouldn’t leave because I got a dungeon I didn’t like.
So that first link is about adding a blacklist system into heroics and battlegrounds and this is what I have to say about that.
Blacklisting BGs and Dungeons So EVERYONES Time Is Not Wasted
Having a blacklisting system in RDF takes the random out of RDF, if you don’t want to get specific dungeons then search for specific dungeons. “But we’re doing RDF for Valour Points” then do what it’s actually called and do a RANDOM dungeon. The second you can influence what can or can not be in the pool is the second it’s no longer random. Doesn’t matter if you can only take out one dungeon you shouldn’t be able to influence what you get in any way.
The OP in that thread is someone who leaves the group as soon as they get a Strand of the Ancients as their BG or a Deadmines as their dungeon, leaving the other 4 to sigh and either also leave or wait for a new tank. I’ll reiterate that such players shouldn’t be adheared to in the least, it’s toxic behaviour that shouldn’t be justified what so ever.
Player Abandonment:
These people shouldn’t be catered to and quite honestly should be punished harsher for leaving but would likely effect the kick punishment too, if they were seperate I’d honestly suggest a compounding punishment for repeated leavers where they’d be locked from RDF for increasingly longer times endlessly stacking.
You’re suggesting to remove it entirely from the pool? You do realize that there’s pre-bis in that dungeon right? Reducing it’s frequency is fine honestly but to remove it completely makes no sense at all.
Doesn’t take long to do so not really needed.
Keep it as it is, there’s no need to change something like how much Valour points one gets and even if Blizzard did, it’d likely not be enough because the people we’re dealing with are too impatient
