This was traditionally the case in 3v3 because the roamer had most of the initiation (and other) tools, and they also had to be the most on top of map awareness.
Iirc the C9 Roster is DNZio, Gabevizzle, IloveJoseph, OldSkool, and MaxGreen. ttigers is a sub - a role I would have been much more used to seeing him in after Liberation X disbanded than in the recent past. For reasons I am about to clobber everyone with, I feel that Gabe will actually be the shotcaller.
edit, my reasoning is moot, they just announced their lineup on twitter.
I can’t say much about player qualities atm having not watched any of them extensively, but I can say a few things. AFAIK iLoveJoseph and OldSkool have always been damage main, and while they have had very good games they don’t seem to have the “x” factor that DNZio does. Likewise, MaxGreen has come a very, very long way since his start in VGL as an “unspectacular” roamer. However, he also lacks experience in the competitive scene at least from the highest levels, compared to Gabe and Zio. This is not to say any of these 3 are ruled out, I’m just pointing out reasons that I think the shot calling role is less likely to go to one of them. I really wouldn’t mind if Max ended up being the shotcaller and its possible - all of them are new to 5v5 - but I feel its unlikely due to relatively little competitive experience.
Gabevizzle has been around a really long time. I know he is a competent jungler in 3v3 though I don’t know how he will do in 5v5. I certainly don’t know if he is “world class” as a carry player in any role. I feel its most likely he transitions to jungle (damage trading is far less important here). That was his role on the one team I can remember that did not run him as a captain. Additionally, I primarily remember iLoveJoseph for playing melee heroes successfully in 3v3 (kind of like Mango?). While this means that he technically transitions to jungle easier than Gabe, iLoveJoseph can transition into focusing on top laners such as Blackfeather (which he already has played), Lane Taka, and so on. Whatever he wants. Meanwhile, GabeVizzle hasn’t laned competitively afaik and so he would fit in much better on the team as a roaming player who can help shotcall. I.e. the jungler. Due to roaming experience Gabe can probably flex into defensive junglers more naturally than the offensively minded carry mains. He has also played some very interesting roamers before like Koshka and Taka that are much more viable in 5v5 in specific scenarios while translating into the jungle role reasonably well.
It is also worth noting that Gabe generally seems more unflappable and stable. DNZio used to have some issues with instability before.
From what I remember of the videos I’ve watched, DNZio is likely the shot caller for his 3v3 team (I think he normally shotcalls on voice chat on his youtube vids). ttigers is not necessarily wrong, but DNZio is a much more garrulous personality with none of the shyness that ttigers exhibits. Obviously, Max is newer and doesn’t seem like the talkative type either from a distance. So DNZio won’t have 0 experience in this role. However, map awareness at a high level is harder in 5v5 and much more critical. DNZio’s primary strength is still clearly as a carry in knowing how and when to engage or maximize damage. Especially snowballing. I feel its more likely that he is potentially the initiator/main carry in damage fights from the bot lane, playing more to his observable strengths. This is not to say that he cannot shot call, it just feels to me that he will be best suited to focusing on snowballing the bot lane and gaining lane pressure the others can work off of.
So at the end of all this, I see:
iLoveJoseph as top laner
OldSkool as midlane (mages, Vox, anyone?)
DNZio as Bot lane, possibly the main initiator/carry in team fights.
Max is obviously roaming.
GabeVizzle works as a pseudo roamer with damage potential, and the strategic shot caller. (Remember, his role will involve a lot of roaming already.)

In this reddit post, some of Tribe indicate that DNZio is probably the main shot caller. They would know better than we would, though it would probably be a disadvantage for them to reveal who is the shotcaller in competition (so they don’t hard confirm anything).
Of course, I’m hoping to see team @idmonfish face off vs them. SEA is not particularly renowned for their mechanics compared to EA and even NA AFAIK so I’d really want to see how their macro game plays out (and how much their mechanics improve). Or maybe I just want to see Idmonfish on stage again :stareyes:
