I reckon they had very little impact when everyone realized that the race changes affected every race and everyone recieved 3 race change tokens as compensation.

Nothing have change to me.
- Khajiit still a DK healer
- Breton still Templar heal
- High elf still petsorc
- Nord still frost tank warden

all fine

Edit :
I've use token to change some look, not race.

For me I changed

Nord nightblade to Argonian
Argonian dk to Nord

Just a straight swap around and only because I believe the passives will work better that way for race and class, changed their names too and changed the name on one of my others toons

The best thing was getting to change their appearance so now I like their look too

As far as I can tell most people did not complained about the fact that they will have to race change, but rather the fact that racial rebalance did not deliverd what it promised to do:

Just read what were the original racial rebalance goals and problems that they were supposed to solve. You will notice that almost non of the problems have been solved and right now (after update 21) races have even more limited use. Most races have been further shoehorned into one specific role / use, often without even beeing bis or close to bis at that role. Almost 1/3 of races currently have almost no use (Wood Elf, Argonian, Khajiit).
I would even dare to say that out of 10 races we have, only 3 or 4 that are vailable to do content and the rest have nothing unique to offer.
In short: People are Extremely disappointed (unless of course they mained Breton, Orc, Nord or Redguard).

Imo, each racial skill should got 3 choice (1 base + 2 morph)
1 for stam, 1 for mag and 1 for health.
Then you can easily balance diversity.
