For anyone considering getting a Mimesis implant set for incursion Leshak... don't. It's 134s to equal non-Mimesis Leshak with both ships having max skills and a Pashan 7% RoF implant. About 145s without the implant.
You could maybe bring it down to 120 or 130 seconds, but that would still mean the only time the implant set it better, is during a long tower bash. And while that sounds nice, a lot of time, you're shooting enemy ships, which all die way faster than 2 minutes.
