I leveled an agent to 50, Crowley-Mathers, who adds 650 attack points if used as a support agent. My combat power when I used her increased by 35, from 869 to 894. However my IP didn’t change at all, remaining at 523.
Since IP appears to be the best index of DPS (isn’t it?), or at least the most used, does this increased combat power really do me any good in terms of damage dealt? If not, why use the support agent at all and, if so, why doesn’t using the agent support bonus improve my IP?
