Oh....so no crowd control effects...?!?

And they hit for 9000.....oookay.....

LOL, yeah, the first two guards in Ramps one-shotted our rogue the first time I was in there when he went to sap one.  It is funny in retrospect. 

This is why tanks need to be somewhat well geared for them.  Obviously they do not hit for 9k on +490 def plate. :) Which is good since your tank is gonna have to tank them both.  Easy as cake when you are well-geared, almost impossible if you are not.  (Heh, or like the very first time I ever did a heroic, I was with a tank that was newly 70 and a bit squishy, so we simply did everything we could to take down one of them before we wiped and tried again.  I'm sure many people have had this experience.  It is hilarious later to remember how hard they seemed - though all instances are like that, I suppose.  Heroic Slabs, for example, was impossible the first time I tried it, but once you are in T5 equivalents you can four-man it.  Again, it is the trash, not the bosses that are the challenge....)

Heroic Black Morass is another great example.  The three boss fights aren't much harder than in regular (Aeonus, the last boss, hits like a girl even in heroic - I can toss the tank a HoT and dps) - but there are like twice as many adds spawned from the voids and they seem to have a few more hit points.  So clearing all of one void before the next opens up becomes more of a challenge (and there is little time to mana-up as a result) - as does protecting your healer, who will be under attack more.  Unlike most instances where so long as your tank and healer are well geared you can take a bit longer to take down the trash, BM is all about dps. ^^

Fun stuff :)
