I need expert pally help! I dinged 50 on my paladin a few weeks ago and recently got a high enough i level (80) that I felt comfortable speed running/ myth farming Brayflox HM.

I've done it countless times as an i94 DRG (my main class) so I know where to run and how far to pull and such.
Sometimes I'll have a perfect run, but then there are some groups I just fail miserably with. I'm now wondering if I am being carried by awesome healers and aware DPS.

Do you have to hit each mob as you run up? I usually just shield lob a few along the way to the ramp area, wait for them to catch up, use HG then CoS, then Flash a few times and Sentinel. I'll then start the Riot Blade combo and run around avoiding the cone attacks while Flashing mobs that are turning yellow on the enmity icon.

Is this correct? Sometimes it works fine, sometimes I die, sometimes I lose control of the mob and a healer or BLM dies. I've seen a video where they Flash each mob as the run by. I've tried this with the same worked fine/ failed horribly results.

Honestly I power leveled with a lot of fate parties and didn't do many dungeons besides the early ones. I still feel like a new and shitty tank.
I haven't had an "AHA!" moment and still struggle regularly. Do I just need more experience?
Thanks for any guidance or tips here.
