Jhon and Nelson have done a good job of pointing out the main benchmarks, but that Mence spread also allows it to survive a Choice Specs Dazzling Gleam or HP Ice from Tapu Koko from full health, which can decide some one-on-ones against another popular meta threat. Further, the extra bulk allows Mence an easier setup against some weaker super effective attacks (i.e. Cresselia Ice Beam, Intimidated Mimikyu Play Rough, etc.).I've seen this spread for Bulky Mega Mence before and I'm considering re-ev'ing my Fast Salamence into a bulkier Mence. However, could somebody explain to me what the EV distribution is meant to accomplish?
