Yes.
No, seriously, it is.
And the reason I do it at the beginning is that many people will sort of hang generally near their clock spots in general when you do, meaning if a clock spot mechanic turns up people are more or less already in the right spots. Moreover, it gets people thinking about those spots from pull #1; in my experience, when you do 5 or 6 pulls and then hit a mechanic and assign clock spots, there's a non-zero chance that someone has now basically ingrained "I STAND HERE" wherever they were for those first 5-6 pulls and then you waste another couple of pulls before people actually remember to start standing in their clock positions.
Moreover, if you see a mechanic that drops a stack marker on each healer, you can scramble last-minute and hope you end up with two sufficient stacks (rather than both tanks and three DPS stacking on one healer, leaving the other healer and one DPS to die)... or you can have set up light parties ahead of time and go "Oh, there's a stack marker on each healer... better get to my healer."
(And there's a decidedly greater than 0% chance that there will be a light party stack on each healer at some point in a fight. They basically use light party stacks for seasoning in these fights... like adding a pinch of oregano, if oregano was prone to exploding.)
Same with role buddies/quadrants, etc. I have found that getting people to keep those in mind from the beginning tends to make the later pulls go much more smoothly if it turns out you need them.
I mean, that is correct? That is more or less what people are telling you in this thread.
Again: many of us have said would assign partners from the start whether or not we know a fight needs them, which is the point here. The vast majority of higher-end content in this game has some combination of clock spots, quadrants, role buddies/partners, and light parties.
My usual "okay, let's square this away before we start" is:
- Clock spots. (Drop one waymark, people stand around it.)
- Light parties. (Drop the '1' and '2' waymarks, a tank, healer, and two DPS gather on each.)
- Quadrants/role partners. (Drop '3' and '4' in addition, a Tank/Healer and a DPS stand in each, thus partnering up.)
Hey, cool, we have now accounted for the vast majority of things we're likely to see ahead-of-time. Those may not show up -- maybe you don't need light parties! Maybe you don't ever have quadrants or role buddies! But if they do, we've already sorted them from step 1.
I'm not saying this person wasn't planning to give away mechanics; I have no way of knowing. I'm saying -- as are others -- that many of us think that just the act of dropping waymarks is insufficient to find them guilty immediately. It's sort of like going "This person drives a red sports car, so they obviously must always break the speed limit." Sure, there are people who drive red sports cars and break the speed limit. The person you're accusing might, in fact, be one! But just owning a red car is not sufficient data from which to draw that conclusion.
I mean, you do you; when you're the one running a party, it's sort of "your way or the highway". But if you're looking for validation of that choice, I don't think you're going to find it in this thread. Many of us do run blind prog parties, and still will drop waymarks to set up positions ahead-of-time.
