Just my 2 cents on the ideas and how I would think many players could exploit those:

#1: setting up 4 additional accounts and setting the silver price very low could actually greatly benefit my main account. 

#2 How do you differ FTP gifts to an account? You would need separate entries for gems earned, bought or awarded

#3 see my comments at #1: I would build up many secondary accounts, earn the easy shards, gems etc. and transfer them to my main account. Next secondary account

#4 Shifting? From the normal market in which only shards are relevant? 

#5: $500 are around 50 packages of montly gems (2140 at the moment). After playing for 50 months, you have around 107.000 gems. To get them in a life time, you would need to play 89 years to get the same amount of gems. Even with 1000 gems each month or 50$ for the life time package, that would be nearly 9 years. The number would have to increase dramatically like 500$ and you get 10.000 gems each month. 

#6 I think that many players would go to Comicon and physically tell the devs what they are thinking about the latest changes. It might be a very intense experience for all...but not necessarily a good one.

#7 is already happening

#8 will never happen: Imagine the possibilities to cheat and the dramatic decrease in income for Plarium.

#9 A better communication system for clans would be much appreciated...be it a vocal one or a simple ingame forum or whatever. The current state is very well for a game in the 1980s but not much more

#10 Listening to the CCs and player base would be much appreciated. Plarium has already all the tools with the CCChannel...they are just not listening

Indeed, a lot of the interfaces the game is so outdated. For example: Somebody left my Clan right now without saying goodbye. We could see from the number of members that somebody left, but as there is nothing like a log for such things it took a while to find out who. Another place, among others (shard mercy system), where you need external progs (or pen and paper 🙂) for a propper management. Hey Plarium, we have 2021! Do you really think pen and paper are the right tools that help to play your game?
