I wish that once you got far enough in the main quest line where you had to choose between blades or greybeards depending on your decision why not give you the choice to eliminate either side depending no matter who you side with. This is one of my biggest issues with the game how some factions you can kill off and some you can't and I understand its because of some npcs being more imporant then others due to quests but why not allow the choice to eliminate any faction or npc once these quests are either done or far along where the faction or npc is no longer as imporant where killing them would not matter. This would make it more real and mor rewarding. I mean I hate it how in Riften its so rewarding and worthwhile to play as a thieve nd join the thieves guild but if ou play the good guy or hero role it's no fun because you can't really do much to turn the town around because You can't hurt Maven and her BlackBriar family and you can't stop the thieves guild if you wanted to be a good guy/hero due to quests and so on. Why not make just like the how it is with the Dark Brotherhood you can join them but if you instead kill that Brotherhood character that you first meet then the quests change and you can go against them and kill them if you want. Same should have been done with Riften and the thieves guild. As a thieve or bad guy there's so many quests in Riften but as a hero or good guy it svcks there should be more quests and quests specific for choosing the good path and there ain't.
Now my last issue would be how as far as I know and correct me if im wrong but the only way that know that you can become a werewolf is to join the companions which to me svcks because just like how easy it is to become a vampire in skyrim the same should be for beoming a werewolf and you shouldn't have to join a faction to become a werewolf. I like and understand why and how it happens with the companions and think the story is great and love it how you that you can choose to become one during the faction quests but you should be able to become one through other ways in the game. Also if they did add to the game other ways to become a werewolf another thing they should add in if possible would be other ways to get rid of the disease and also be able to cure yourself whenever as long as its not to late o to far along. I understand why it's not easy to undo werewolves curse of the companions due to how they became werewolves and that its a curse but for people who were become a werewolf through the game by contracting it from werewolves that you can encounter through out the game world you should be able to just cure it like you do with the vampire diseases because unlike the companions werewolf curse you got it by contracting the disease. Also of course depending on how long you've had it and then beomes more difficult and requires another method and not just a potion but that would be up to the developers of course.
Well these might be minor issues but I believe if these changes were made the game would be even more fun and these changes add even more replay value to a game that already has probably the highest replay value in any console game to date.
