This is by far the worst thing I have heard in my 6 years of PR.So long story short, we will be removing Kashan at some point in the future.
Why should it be removed? if it's 'hated' as you say then admins just don't suggest it on their server? What will it change to remove it, servers with people willing to play it can play it, and others just don't!
Maps come and go, but very popular maps aren't removed (just take muttrah), kashan being one of them. It's either people love kashan or hate it, there is no middle. Therefor you'll obviously hear a lot of people who hate it, while there is actually another big part that considers it an awesome map.
I don't know if I am the only one, but to me kamisiyah is nothing like kashan, I can't even understand it is the one supposed to replace it. Just the fact that kashan has a gameplay focused on the bunker complex surrounded by some high terrain makes it unique, and by far not similar to any other map on PR!
Kamisiyah is more of a mix between Al Kufrah and Burning sands in my opinion.
