The effect of center of the universe is affected by the quality of her gear, it's not 50% flat. Also, there are plenty other buffs whose effects are divided by the number of buffed crusaders.

For Grok, Sisaron, SQ, etc. the ability says that the bonus in divided by the number of affected crusaders, so I agree that Karen should count since she is affected.

But I don't think she should count for Turkey's Short Circuit ability, which says it zaps a random "adjacent" crusader. If I remember correctly, in the past she was able to receive Turkey's buff without pulling it away from any adjacent crusader, giving a total of 4 crusaders able to be zapped at once. Now she acts as an adjacent crusader when she is not, which is incorrect in my opinion. Since in the case of Grok, she isn't a target of his buff like the column in front of him, she just receives it and is affected by it. If she was targeted she would take the buff at full. Now she is being targeted by Turkey instead of just receiving it, which is inconsistent.

Now this all translates to a loss of the buff from turkey for about 25% time (10s/40s) if you are using a single dps with ~100% of your total. It is not very significant and does not diminish the effectiveness of Turkey, but it is annoying to see constant fluctuations in dps.
