I have been wondering over the past couple of months what the general attitude is with the current system of tiers, where a new tier will completely change the face of the game, removing most reason to enter the old raids besides achievements like a new mini expansion with new lvl cap. As i see it the current system as it is now tries to have every player at the same tier at the same time with bosses hard enough for the pros not to clear in a week and easy enough so that every player can see all content at roughly the same time. my question is then what do you prefer. a system tier system like that of TBC where the best players would clear and gear up for the harder raids faster cause of their skills, leaving the newest players on the older raids simply due to their gear, so they would have to use time farming old instances to get the gear to enter the next Tier of raids instead of the system as it is now where every player that farms HC's can get the gear from the second newest raid without having to enter a old raid.
for instance: my pala which were my 3th char to 80 never entered Naxx or Ulduar but could easily get the gear required to enter ICC and ToTGC just from staying in HC's
i would prefer the system where you had to raid T11 to get to T12 to get to T13, not because i don't like a system where new players don't have to farm old raids to get to the highest Tier but because i feel like crap when i know that by the beginning of a new major patch all gear i have will become equal to everyone else and have to start from scratch since you can just buy the gear you would normally raid to get
note: i am not a HC raider and as such don't get to the items that aren't possible to get even after a patch but even these items aren't that useful after a patch since the first easy bosses will drop higher item lvl loot
