I really just wanted to share the experience so that everyone can find their own "meaning" in this story.
So here i was, trying to level up an alt to finally play the Thief Guild and the next Dark Brotherhood DLC (My vet 16 tank is really not the character i want to play in a "stealthy way") and in my guild chat i read "is there any tank willing to come and help with dialies?"
"Why not" i tought.. "after all even if i stopped playing my tank on a regular basis i can still use it to help guildies in need".. so i switched characters and joined the party.
One of the players in party was not a guildie, just a DPS that decided to join for the gold pledge in banished cells.
The first thing i did was telling everyone that i didn't have experience with vet dungeons so they had to tell me what to do "step by step" on boss fights... and the answer i received from the DPS was: "no problem, this is an easy dungeon", just before seeing him rushing in on his own.
And well... yeah... i got to admit he was kind of a "super" dps in terms of damage.. strong enough to rush on his own into rooms and kill most of the enemies by himself.
We eventually arrived at the first boss and killed it quite easely only to be "rewarded" in group chat with a: "uhmmmm... this took longer then usuale" from our fellow DPS.
We kept going on and reached another boss... during the fight our healer had a spike of lag and we wiped.
"how could you die with this boss.. it's a soo easy fight!"
Well the lag was explained and we decided to just keep going and, after that, we managed to reach the final boss quite easely and with no problem at all.
Before going into the fight the DPS stops everyone and start explaining me the "perfect strategy" to kill the boss and get the gold pledge done: "so tank you just have to aggro the adds during the whole fight while we nuke the boss down".
"ok" i answered... expecially since it was my first time in there.
We went in... and we wiped.
Second try... and we siped.
DPS: "guys how can you possibly die i here it's a so freaking easy dungeon!"
Third try... wiped
Fourth try... wiped
DPS: "Sorry guys... with you it's impossible to complete this dungeon your damage is just not high enough" was the last thing said before leaving the party.
So we were left in three and decided to search for a new DPS.. eventually finding a friend of a group member available to come.
As soon as we were 4 again we started one more time with the strategy the "super player" told us to use... and we wiped.
That was when one of the "normal players" said: "ehy, let's just kill the adds until the boss has 10% of health left.. then we leave 3 of them spawn and we kill the boss super fast.. that should do it".
First try, boss killed, gold pledge done.
As i said... i leave everyone finding his/her own conclusions ^^
