Having used up all ten spots on my server, seven of the ten are at level cap by the way, it comes to no surprise to finding myself using the LFG tool for hopefully quick and easy runs to gear up my alts, since I don't like leaving characters at 80 with poor gear.
However, I've been noticing a disturbing trend in dungeons like Utgard Pinnacle.
For bosses such as Svala Sorrrowgrave and the stasis room, they can be easily bypassed and though I often hear the excuse that the time saved by skipping them would garner more badges that way, I remain doubtful. That goes double for you if you're a DPS class with no healing/tanking alternative.
Frankly, I find it rather frustrating, just hitting 80 and hoping to get some use out of the LFG tool, only to find bosses with loot you could potentially use because other members of the group are already decked out t9/10 and don't have the patience or understanding to remember that were once like me at one point.
As easy as it is to put the blame squarely on the shoulders of the players, it's far easier to put the responsibility of this on Blizzard's part, on account that they made the instance in the first place.
Did they made it so that they could be skipped intentionally? I doubt it. But then again, they intentionally left certain classes with only the choice they had for raiding was heal or don't raid. So, as easy as it is for me to resort to my biases to make the developers sound as incompetent as possible, I am going to have to left them go on this one. Since you don't exactly make content that players should miss, even if you've done it countless times for an item that doesn't want to drop for you.
