Where is the jsutice?

Playing with some equipment tools i found out that this is so unfairly easy to build a insane HP and armor capped druid tank without even trying to visit the 25ppl raid instances. All you need is to farm 3-4 heroics daily... farm your 500+ Badges of Justice and you're done. There are only 5 other items that you might want to get from other sources, and here's the list:
- Vengeful Gladiator's Dragonhide Helm for some arena points.
- Merciless Gladiator's Dragonhide Spaulders extremely easy to farm 11.250 honor points and no rating requirement.
- Moroes' Lucky Pocket Watch which drops off the 2nd boss in karazhan and should be very easy to get.
- Commendation of Kael'thas which drops from Kael from heroic MgT, and this instance is not that hard for the tank, it requires much more of the team play than decent tanking gear.
- Violet Signet of the Great Protector a reputation reward from the Karazhan, which is more like Badge of Justice farming source after you do it for a couple of times, so you're reaching 2 goals at the same time.

How much time you need to get this goal accomplished? 1.5 moths and you're done! Comparing to months of 25ppl farming for almost the same gear... ouch!
