I am a relatively new player. I get the impression (from runs as DPS) that there is a certain correct way to pull / tank Meridianum and Praetorium — runs that go smoothly have a very methodical, coordinated pace like everyone knows exactly what to do.

I tried queuing Tank for MSQ today and was placed in Meridianum. The run went fine, no wipes (it's hard to lose MSQ Roulette) ... but it also didn't feel as smooth and clean as runs where I'm DPS.

I'm pretty sure I messed up a few expected rules for the instance due to unfamiliarity with Roulette groups' preferred style for speed-clearing it. (For example, not being sure what to do with the Colossus boss that summons adds; not being sure exactly when to stop pulling stuff and let the group AOE... etc)

Could someone provide a step-by-step of the correct way Roulette groups expect these dungeons to be pulled and handled? I want to learn to be a better Tank and not make content unnecessarily messy.
