Right from the horse's mouth. So yes, it is indeed factual.

It is important to realize, people's conception on balance was/is completely skewed. Since paladin (OP, not intended) allowed for people to tackle coil without the proper gear (its an i90 dungeon, highest gear before then is is i70, so everyone was going to coil under geared. Again here I am relying on logic to tell me that the missing iLevel of gear is an issue), means that the Warrior (perfectly balanced based on current implemented gear progression) suffered from a backwards content release where we skipped an ilevel of gear.
Once warriors caught up into what is the proper gear level (not over geared, remember coil is i90) from mythos gears or the precious allagan pieces that dropped, you then saw warriors start to tank and even now MT twitanna based on what the progression would have been if warriors were in i90 (the proper gear).
Its pretty easy to see that from both a logical and informational standpoint, the argument is completely valid.
People just don't like the idea that they've been clearing content a bit easier than they should have been.
