If I may add a few things to some of the topics now that I am present? 

@ The Topic of Learning Shouts: The Greybeards themselves study their entire lives, a lifetime of practice, meditation, and harnessing the power of the Thu'um and they barely know a few full shouts. (FusRoDah, Whirlwind Sprint, and Clear Skies) Ulfric Stormcloak trained with for an undisclosed amount of time, and learned what is labeled as "a shout" which is the same he used to kill the High King. A "dozen or so words" would be one thing, but to learn to shout with those words as well would demand you spend a life-time with the Greybeards.

@ The Topic of a Mammoth Mount: Oddly enough.. this isn't the first time this topic has come up in an ESRP I was present for.. I did one quite some time ago with some close friends and a random joiner wanted one, we all voted against for a few simple reasons. Even though this person only wanted it for a "Pack Mount" it is still a Mammoth. It still wields tusks, it would naturally and realistically act as one, and on top of that Mammoth Calves are roughly the size of a large cow, and in the lore they are only tamable by Giants. Of course not everything this rp does is lore-strict, but I still feel it would present OP-opportunities as it is a gigantic Mammal wielding massive ivory weapons and the strength of a titanic mound of flesh. I vote against the Mammoth, sorry.
