@Flambeau83 unfortunately, you are bad at math. Let's say you have 20,000 angels at 6% per angel. If your base profit is 100, then your modified profit is 120,000 (100*(20,000*.06)). If you spend 10,000 of those angels for a x3 multiplier, then your new modified profit is 180,000 (100*(10,000*.06)*3) so it is worth it.
