As many times has been said, "it's realistic" is a bad argument for the game design of current AoP. There are so many unrealistic things, that trying to skip them and add something realistic just for the case of having something realistic is useless.
Cirn0John often use argument "it's fun" for the game design. It has own problems too, first and obv "fun" is subjective. Thus the real argument they mean by that is actually "it'll troll people and I will have fun". Second, something could be fun one-sided and not fun to fight against. Example: red/yellow nukas which were supposed to be "joke items" by design, in real were balance and game mechanics breaking items of dominations. After numerous nerfs, they still might be partially the same, fortunately not used widely.
Still even trollnukas extended the possible tactics/game mechanics arsenal. So after balancing, they will certainly find own deserved place
Now back to HTC malus or any other suggestion to introduce, the questions are:
1) What exactly is going to be archived? (what problem is being solved by that?) How will it make the game better?
2) Is it the best way to achieve that? Are there alternatives? Are there side-effects?
If main idea of the CTH malus is "some real night feeling", than I'd suggest registration by the passport/id and deleting characters after death for "some real life feeling". Same amount of realism and fun.
On other hand, I'd agree with something, which would be positioned as "Being more realistic and thus more intuitive and less frustrating". But I don't see how missing just because night makes the game less frustrating.
In the insurgency I don't think I ever miss because of the night map.
