In a recent post of mine, I aired my views on how I perceive the rights on loot that drops in an instance.
This behavior mindset I got is, apparently, the reason there is a tank shortage.
To this I call bullshit. It is not because of people like me, who needs on upgrades to their gearsets, that cause a tank shortage. Or healer shortage, for that matter..
It is because people prefer to do the role as a damagedealer, with no real obligation to a group, except dealing some damage.
It's mainly because of the retards that bitch and moan, putting the blame on whatever happened on the tank or healer. It's the ones who can not take a single ounce of self-criticism or responsibility. The ones who prefer to be carefree, "chilled out", cool guy that prefer socializing with their friends in the game (or out of game) while the rest of the "NPC's" in the group does all the work for them. The retards.
It takes a certain mindset to play as a tank or a healer. You can't really slack, you have to pay attention on what's going on or you'll end up having a cup of tea with the spirit guide, discussing how cool that new death animation they put in in cataclysm looks.
Claim something different and I call bullshit. Yes, you can slack some when outgearing the instance, but you can't stop paying attention to what you're doing or someone in the group dies. (Of course, letting people die on purpose because they are retards and they'll cause less hassle to the group by being dead instead of alive is all well and good, but a different topic.)
People do simply not want to be a tank or a healer. It is much, much easier to be a damagedealer. That's the reason for tank shortage. Not people rolling on stuff that's an upgrade to them, no matter what spec they are currently in.
The whole mainspec and offspec "unwritten" rule is a fallacy now, with dualspec and the LFG tool in the game. The "social glue" the groups had before the LFG tool, where you had to manually gather the group is gone.
While you can still gather people the old fashioned way now, it is way to much hassle when you can simply click on the LFG button, queue up as the roles you can go as and press the "Find group" button. The LFG tool is simply that much faster and easier to use for this purpose. If you want me to spend more time in the game doing it the old fashioned way, then I call bullshit again. You wouldn't do it, so why should I?
The funny part about you "tank/healer shortage reason" people though, is the mindset you got. According to you, a freshly dinged level 80, who's leveled as a damagedealer (by questing, it's far superior to leveling speed than instances), that player is not allowed to gather gear for tanking or healing in heroics if having joined as a damagedealer. Because then that player is the reason for tank or healer shortage, no matter that the player is to become a viable tank or healer.
You guys are funny. :)
