Thank you guys. I've already thought 60% would be way too much, however I just need to be confirmed.

So... I think it's not worth using the Boost, right? Yeah from 10% to 15% or from 20 to 30 may sounds good but the 5-gem cost is precious (breeding tree, ivory island, temple, quest... omg). Besides, I've heard many of you who get legend without using boost.
