Playing a Nightfall or weekly Heroic?? By all means, cheese him from the shrieker room. Playing a Roc or lower level? Get your a$$ out here in the main room with the rest of us. You do realize that staying in that room causes a sh!t-ton of extra wizards and boomer knights to spawn, right? There is enough crap to deal with out here without adding to the misery.
PS: stay off the damn platforms, too. See above
Edit: dang. Looks like I touched a nerve here. Hopefully the shrieker room campers will see this and heed the advice. Sure would make life a lot easier!
Edit 2: as I mentioned above, I have NO ISSUE with using the shrieker room on the Nightfall or Heroic. Hell, I use it myself. This is strictly directed at people who hang back there during Roc strikes or lower.
Edit 3: to the "i paid $60 i can play how i want to so shut up" crowd....you are absolutely right. you sure can. and i can go sit my a$$ in the room behind you, only getting up to periodically drop my titan bubble in front of you or to run into the 3rd back room to make Phogoth's health regenerate. after all....i paid my $60 too, right??
