Hey guys, not to hijack this but I had a similar question as I want to do DRK but am leveling the other 2 to 30 just for the cross class. I'm a healer mainly and have all 3 at 60. I played Sashtasha with my level 30 DRK and had no issues at all. I then tried last night with my level 15 Gladiator (was 17 by the time it ended) and I bought all my gear from the market board which I think came from Sashtasha, and it's level 15 and has the green shading like it's a good item type thing. Anyway I forgot to check if anyone was level sync'd but last night was so hard, every few seconds the other 2 DPS would take aggro. I'd do flash, nothing would happen, do it again, same thing. Shield Lob I was convinced by the end doesn't increase enimity as it did nothing as well. They had to almost stop attacking for me to get aggro back. Didn't happen all the time, maybe 5 or 6 times but it was so hard to get it back or keep it. Am I supposed to be popping flash often during a battle? I was constantly running out of MP using it so much to try and keep it up (mixed with whatever that combo ability is that increases it as well at 200 potency, I forget the name of it but the icon is yellow.)
I assume it was due to level sync, especially if one of the DPS was much higher, but I had zero problems as DRK, but found it happened way more as Gladiator. Probably because I'm such a low level though. I think I was also nervous that someone else would be like wtf are you doing, since like the post above said Flash doesn't do damage. For the life of me I can't remember what other tanks do when leveling as even though I heal I don't pay that much attention lol.
