The EP made it harder for me to make interesting contracts.
It’s too useful
That’s the crux of why the phone was so hated. It was seen as an in-game cheat code. I can, today, download a trainer and play the game as an invisible super-soldier. I can shoot every single NPC in the face and retain Silent Assassin. I can run from the start point right to the target without using a disguise, shoot the target with an unsilenced shotgun, leave the body where it falls, and exit the level and STILL get a Silent Assassin rating at the end.
A lot of players saw the Electrocution Phone as an in-game, sanctioned version of that. It made contracts “harder” to create in that the players wouldn’t need to use the same routing or tactics that the creator used. It would undoubtedly be very frustrating for a creator to go through the process of creating a contract, complete with a detailed route in mind and a prescribed kill method and then see a player just toss a phone on the ground and wait by the exit.
I imagine it’s somewhat similar to the developers watching the speed runs and seeing all of their hard work just ignored as a player finishes off the entire map in 10 or less seconds.
It’s still a problem for the creator though, not the player, as a differentiator. As a player, I have to side with Heisenberg. If you don’t like a thing in a game, just don’t use it. I almost never use Fiber Wire or any variant of it nor do I ever use the suit-and-tie outfits. I wouldn’t demand that IOI remove them from the game (and to do so would be asinine because they are so tied to 47 as a character). Their existence doesn’t impact me much. If I do come across a contract that requires fiber wire or the signature suit, I just ignore those requirements and take my less-than-5-star rating at the end.
Both points of view, that of the creator and that of the player, are valid, but they are also contradictory. There’s no way to reconcile the frustration of the creator in seeing their intentions ignored with the frustration of the player in having an (relatively) easy kill method removed just because it was “too easy”.
