That's the daily thoughts of the average thieves in all of the 4 installments of TES. Without mods, the contempt of The Nine Divines by functional windows act as an conservative irrational little b-e-a-ch, and our thief's only means of invasion are front doors, and, maybe, kitchen back doors in the fourth edition of the game... mostly on the first option i would bet. Even if the climbing skill is neither in Morrowind, nor in Oblivion, it wasn't very useful for thievery in the late Daggerfall (i dont remember it in Arena), unless you wanted to spend eternal hours on the roof of some building waiting for the guards pursuers to go away (something that will never happen). All of this reminds me of two mods for thieves made for Oblivion: the first one adds a series of gadgets for this class like an underground shop at the Imperial City that sells rope-arrows to climb things etc... this mod combined with the second one that put locks on most of the windows in Tamriel, that can actually be lockpicked, causing this windows to serve as passage to the inside of a house/tower/castle, made much more sense in my personal experience as a member of the thieves guild in TESIV.
So... How do you think thievery mechanics should be designed in Skyrim?
Anyway, without further ado and reticences, i want you to welcome this poll (that, probably, is not the first one about the theme, but let's reinforce our thoughts :wink_smile: ) "Should climbing ability return in TESV: Skyrim?", reply your opinion and thoughts about that.
EDIT: Added another question to the poll, related with the ability to unlock a door by force.
EDIT2: Added yet another question to the poll, related with thieves arsenal provision.
Thanks and Farewell
