Not all universes would have heat death due to different physics, but similar processes, or even simply end of time and new cycle. 
Remember that when Tier Five was in control, portals put huge stress on travelers their first time. 
Most likely, the relatively few survivors of their first portals would be ostracized if they tried to teach others and they got killed/went insane when they were taught.
This would likely lead to hermit esque lives, leading eventually to death by discovery of them in a dimension they have an alternate that's the same as them and the others around freaking out, old age, dangers they weren't prepared for because they didn't exist in their universe, etc. 
Or would lead to them finding and staying at a dimension where other travelers were, adding to the culture of that universe of dimension travelers.  

Logically, at least. Not necessarily canon.

I thought that was only if the travellers didn't have help; i.e. they made their own portals. I just assumed that the portals created were machines or something and that that negated the problem.

Another possibility, then, is that universes filled with a very strong-willed or strong-minded population were those who discovered dimensional travel and had that take off. That would significantly lower the number of universes truly aware of Existence. Or, as another example, enough people were sent through from a universe and survived that they could then ferry ships around Existence. In fact, I can imagine that in the current society of aware universes, that's actually a thing, even a profitable business.

I heard. I watch direwolf20.
I can't get the signs to work but if I figure it out do you want to know how so you can do it?

<Snipped quote by Etcetera>

Economic only. 

Actually I'm saying don't vote for retards. There are a couple other candidates that I don't know off the top of my head.

Oh, really? Awesome.
Sure. I haven't played MC without using a modded challenge map in a long, long while, but if I ever find the time to actually do a normal world, then I'll want to have that info on hand. (After all, Millenaire hasn't been updated in over a year, so I don't expect any bugs that we can fix ourselves to be fixed any time soon unless someone takes over.)
