This is a single player game,
This seems to be the number 1 argument of people who cannot think of valid ones.
Just because it is a single player game, doesn't mean you can throw balance and exploits out the windows. That is very poor game design.
Anyone with a shred of intelligence can see that some things in the game are not meant to be.
Lets take a look at how blacksmithing is too easy to level.
Alchemy, another crafting profession, is very hard to level. How then can you say blacksmithing is intended to be so easy to level?
Training for skills at higher levels can cost over 2000 gold per session. How then can you say it is normal for blacksmithing to cost only a fraction of that amount by crafting iron daggers?
There are actually diminishing returns for IMPROVING iron daggers. It won't increase blacksmithing as much as improving dwarven daggers. How then can you say it is normal for crafting iron daggers to increase blacksmithing as much as crafting dwarven daggers?
Lets take a look at the poor balance of loot.
Though using alchemy/enchanting/blacksmithing exploits, one can craft powerful gear that dwarfs naturally occuring loot like artifacts and daedra lord rewards. How can you say it is normal, if the loot created by the game are no where near the power?
And the number one counter-argument is? Oh, it is a single player game. Yes, lets ignore logic completely and repeatedly say that it a single-player game. Somehow it convinces people that they are right.
Funny how someone like me who presents arguments using valid points, is now accused of having "MMO mentality", supposedly a negative term, while people like the OP are considered "cool".
