My impression is that this thread is for discussing what is happening in the beta, and not to give feedback to the developers. Feedback to the developers is probably best posted on the beta forum. I wouldn't count on what is written here ever comes to the developers attention.
You are partially right and partially wrong,
All CM's worldwide are collecting feedback every week, and discuss those with eachother and the development team.
Your CM is the only connection from players to the dev team.
So to show your voice on live could have an impact.
They are quite aware this is a major change with major impact, now is the international server english like the US server and the Beta server, but how do the german, spanish and eastern block countries respond to these changes?
It is important that people voice there opinion because when things go live, they are in general speaking "finished" and development is closed.
Once this hits live some people will be in for a surprise which might result in a drastic choices.
Emotion is a bitch, for one I for 2 years long had refused to spend a single penny in this game thanks to the change in expanson prices.
I think harvest(harvest set) or easter event(Fire Phoenix) depending who came first was the first time I spend money again in a long long time, recently I spend some money again to buy an expansions when it was discounted and I canme a bit short on diamonds to buy them.
This choice now bites me.
Since this change has the biggest impact on the very active and / or paying customers the impact might be quite severe for the game itself.
People with high tournament scores are more than often paying customers
