Well it's pretty apparent and obvious that they're not going to drop it. This falls right into the same category as the cost to play the game.

The question was how do you feel about the additional fees of extra characters/content IDs.

For example: I would love it if they waived the fees.

Why?

Pros
- This allows a player to freely have access to their mules without worrying if they can afford every single mule for that month.
- To go along with the mentioned above, players won't find themselves in that oh crap moment when you need to grab a specific item they need from a mule, but couldn't afford to reactivate that particular mule/extra character for that month.

Now here's why even though I would love the idea, I think that it would be a bad thing.

Cons
- As previously mentioned, waiving the costs of additional characters on an account would mean less money/profit for the game.
- Even if they did waive the cost, there's a possibility that SE would lower the number of characters that we can have on one account.

Now I'm sure there's more, but that's the main few pros and cons I can think of. Again curious to see how the rest of the playerbase feels about the additional fees for extra characters. Especially when there are those of us who don't agree with still having to pay full price for the game nor for additional storage.
