If you take it, you actually lose. The 10% bonus puts you at 110% life. 10% of that is 11%. 110% - 11% = 99%. Therefore, you have less than you started with, making this “deal” a bad idea. If only the Devs did their math.
Yet, we would get asked “Are you sure you want to leave?” When offered a life reduction.
Completing a high level trial and clicking too fast, nah, they didn’t need those pets, they will have another chance in about 2 years.
Hello 
Just a heads up that this is a currently known issue to the development team which has already been reported.
There has also already been a quality of life request specifically for this issue that the team will take into consideration.
Thank you for understanding
Since it looks like you’re in charge of bug reports now perhaps you would consider resurrecting this :
The place players are supposed to check to see if something is a known issue so they don’t waste time reporting known issue and you don’t waste time reading known issues.
At this time the website hasn’t been updated in 4 months.
