Exactly my feelings. I honestly think that there is no way to compensate the effort someone put in their crews in the old system using the new system.
They should at least set up a limited time period where you can: - convert to the new system for free. - exchange unneeded crews for crew books.
I also believe that Crew 2.0 can not be stopped by the players - this has already been decided for us. I´ll still play, but I won´t buy anything ingame (not even with gold I already own, much less with real money) because I´m sure everything will be changed/nerfed in a few weeks. And it will serve me as a lesson to not get invested in wot any more, just not worth it.
Your effort is not wasted in any way. You will still be keeping the XP and your investment on your new crews. You will still have the advantage
The conversion IS free
unneeded crews in your barracks will be converted to crew books.
Please watch the video, read the article and watch the live Q&A and you will find the answers.
If it was already decided then we wouldn't waste our time in doing those sandbox servers, have those conversations with you! Please go on the sandbox, test the changes and fill the survey because you can have a say in that

Well I'm glad I have 40 tanks in my garage, of which at least 10 are pointless low tier gift tanks with no crew.
So even if I have to manually convert each crew and splurge gold to get the most out of the system (which I'm sure will definitely happen) at least the blow won't be too hard.
But what about all those players with lots of tanks and lots of crews?
Also, disappointed that "zero" skills will be erased and amount to nothing in the conversion, as well as all "special" crews (Santa girls, unique commanders) being demoted to boosters/"instructors". Whoever spends more during holidays and Twitch Prime events will get the best benefit.
... but who am I kidding, this IS a freemium game after all, I should not be surprised at all.
The Instructor conversion is not in any way a demotion! On the contrary, instructors will give you extra skills. After all it's an instructor helping the crew and passing their knowledge 
Zero skills crew members will be converted to instructors.

Tell me how i going to do this with 500 tanks in garage and 400 more crew in baracks? en going to lose my baracks to free retraining books. OMG.
Crew members in your barracks will be turned into training books so you can use it on main crews.
It will take time to retrain all your crews and assign them to your tanks but keep in mind that now 1 crew can be assigned to 3 tanks and all premiums from the same class and nation.

Any change that instructors, which are stupid thing to being with, will ever be free of nation restriction? It's enough commanders are limited that way, but instructors, that's some serious way to screw over with people who got these.
No, in the current system crews are bound to their nation.
Instructors are assigned to your crew, not the tank and they will have to unlocked.
