You can only aggro cap so any extra mobs would be after the team mates. I worried about DE for a couple of levels with my Shield Tank. Key thing is to not always take on two groups and even get a Mezz on the Guardian before it even drops a pet.
Am sure those that helped you find it nice to see someone say thanks. A persons intent is what I would value more than anything. I didn't help you as help was already there, no point repeating what someone else said.
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
I just wanted to make a gesture of thanks to the people here who have steered me, put up with my crap, and just generally gave me pointers to help me turn my main tanker (and his rogue clone) into the unstoppable beasts they are today. The advice, and guidance and support questions answered etc, have been invaluable. Im sure you know who you are and all so, cheers guys, and now let me tell you a story that made me sit up and realise "I have arrived"
This morning I jumped onto my Invul / SS tanker = Power-Drive. He's a baby incarnate, with Tier 3 alpha only. Thats it, but he's got plenty of sets in him and he's level 50. I started to run some hero tips in Atlas. The first featured me quaring off against Rikti and I remember thinking, "wow there's a fair few Rikti in here" so I had a friend from Defiant Events join me, and we carried on. Once the psychic rikti were dispatched, the rest swarmed round.
All the while I was totally oblivious to the simple truth, as I had not played Power-Drive for so long, I had clean forgot he was set to +2 x8 mobs! It was only when we proceeded to do a tip involving devouring Earth that the penny finally dropped. Even then, I carried on, and thanks to the quartz crystals, they did give me lots of pain, nearly killed me once, had to fall back on about 5 insps, and shock horror, Unstoppable to block the toxic barrage from about five greater devoured. But he survived.
I of course apologised to my teammates for putting them through that ringer so cluelessly when I finally realised. And they graciously accepted, but it was a highly educational experience on just what a well made Tanker is capable of.
