Anyone have experience with silent cover talent?
Abbas to your question is not easy. Imo it is good in every place where SS works. SL is different story, cause it is giving HP boost which SC don't have.
But on other hand SC have higher def % than SL or even SS. So it is good on heroes who will not benefit that much from SL Health bonus or just heroes who you want to have bigger defense. Tanks for example, as they will be in close range to enemy or supporters. To many heroes to write here, but examples are Walla, Ripper, Occultist, Phobos, Michael, GS, Sasq etc...
