If Heroes only show in the bases when they log off in the base, I think that would lower the amount of heroes the servers would have to render. Mabye at first most people would run back to their SG to log out, but after awhile, I doubt people will make the extra treck before heading to bed without a good reason. If it still would cause performance problems, then perhaps they could limit it to the first 15 offline people in the base become NPC's, if they were also base guardians, this could allow villian groups to lay seige to the base and give online members a chance to reach their base before it was fully overrun.

You could make it so only heroes who log off inside their HQ are present when offline, and available to defend the base. You could also mabye add 1 room that if players log off in they do not defend the base, mabye have the heroes shown, but in tubes(storywise each player could decide if the tube was suspended animation, a recharging area, or some kind of rejuvination tube). This way if a player logs off anywere in the city, they are not available to defend the base, and when they log on they won't disapear from inside the base, since they were never there.

I think xp debt is a good risk for being able to defend your base, but I think if you get full debt per death you should also get xp for kills. If your hero dies defending the base your hero doesn't re-apear until you log on again.
