The new CP update has really thrown a wrench in the gears of "Let's GO." I was all ready for Generation 2 to come out, and then out of nowhere this CP update changed everything I knew about the gym metagame. I wasn't going to write anything about this new metagame, but I decided I could do a lazy-formatted article to at least give my thoughts about the new gym defender tiers.
These rankings do not only factor in the performance of the defender, but they also take into account a Pokemon's maximum CP. This is the new age of Pokemon GO, where gyms go down much faster. The CP update also promoted a bunch of new high CP Pokemon that players will slot into gyms to avoid being the first to drop out (e.g. Rhydon, Gyarados). Due to the new gym Prestige mechanics, combined with the numerous high-CP Pokemon in the game, having high CP is that much more important for a Gym Defender. Why? Well:
In order for a gym defender to make a difference in a gym, it actually has to stay in the gym long enough to be battled a few times. A Pokemon like Chansey is beastly with its new buff, and I don't have a max-level Chansey to test against to see if it's even possible to beat it before timing out using most available attackers; I suspect it is possible. If it is possible to beat Chansey, then it's not a very good defender. The reason being that players will only ever have to battle Chansey once in order to knock it out of the gym, as it's virtually guaranteed to be at the front. This same principle can be applied to other strong defenders like Wigglytuff, that will simply get dropped from a gym too quickly to be relevant anymore. If you filled a gym with Chanseys, or Wigglytuffs, that's another story. But as general defenders... they're just not up to snuff anymore.
With that said, here's a rough prospective Tier list with some explanations/speculation. Generation 2 will totally revamp this, so I won't be putting tons of work into making this article look pretty. The new Base Stats come from a formula derived by Peter Hatch, commenter on Gamepress. As such, they are calculated approximations, and may not reflect true stats. I've always rounded down, as that's how Pokemon tends to do things. So even if a stat calcs to 200.99, I'd still say the base stat is 200. I think this is how Niantic and Pokemon treat things...
