This information is all coming from the wiki, I am only sharing it

If you take a gander here, you will find that the only followers that level with you in the entire game (Dragonborn not included) are the Dark Brotherhood initiates.

All other followers including powerful essentail ones such as Serena cap out at level 50

Now another thing to mention, you may look this one up yourself however or take my word for it, either way. Call Dragon shout which summons Odahviing to your aid, firstly a fun facts about this shout:

"Odahviing is leveled, but at a substantially higher level than the player until a maximum of level 50 is reached when the player is level 36. For this reason, it may be better to start The Fallen at higher levels when the player will find him an easier target. Also, with the exception of http://www.uesp.net/wiki/Skyrim:The_World-Eater%27s_Eyrie, Odahviing's level will remain as it was when first encountered, so if The Fallen is done early, Odahviing will become a decreasingly effective combatant as the player levels up"

What this means is Odhaviing is as powerful as Ancient Dragon at his best, not a Revered Dragon or a Legendary dragon.

Now if we look at the dragons level list, we find that Revered dragons start appearing at level 59 with Legendary Dragons appearing at level 78.

What makes me question this wiki is when they say things like this, after saying Odahviing maxes out at level 50.

Red Dragons are considered to be the strongest type of dragons. Only one red dragon appears in Skyrim: http://www.uesp.net/wiki/Skyrim:Odahviing, one of Alduin's allies.

I dunno let's just forget about the wiki, can any level 81 players tell me what their experience is, Master difficulty players only preferably. How hard dngeon bosses are, what challenges do you face etc at level 81 other then Ebony Warrior and a couple dragons?

The enitre point of this thread is I don't want to gimp my character leveling to 81, I would hands down use the Oghma Infinium glitch, [censored] grinding skills you don't even need/use past level 59.

I don't remember ever reading anything in the lore that states that Red Dragons are the strongest dragon type.. I remember something stating that they're one of the rarest, but nothing that clearing says that they're considered the strongest.
