First you can't have it all. You have to chose which talents you use at any given moment. The changes also don't make talents restrictive, unless you consider hearthing to be "restrictive". If that is their goal, then its a failed design because if anyone truly wants to change their talents; the restriction of going to a safe zone is not enough a hurdle to make it a difficult decision.
Lets take this change for what it is. Its a nuisance. If you need to change your talents you will. The only difference is you will have to hearth and be summoned to your previous location. That is it.
If they had placed a cooldown on changing talents or a serious penalty like tens of thousands of gold, then perhaps it would have been "restrictive".
