How Groudon will change the meta
So gamepress and silph road have different stats for our newest legendary. This site has 297/276/200 and silph road has 270/251/182.
I presume Silph has it right? Even so, with Solar Beam and Fire Blast I wonder if it'll be a top tier grass and fire attacker. And it's obviously the best ground attacker.

They are LEGENDARY Pokemon, they don't deserve all of these nerfs and they are not easy to obtain. The game forces us to drive all the way into town, find a legendary raid, then try to get people to come to it through an uncoordinated discord group, then pray that enough people will come, and if all of that succeeds then we are only granted a chance at catching the legendary. If it breaks free from all of your balls, then you have to repeat the whole process over and over again until you finally catch it. If all of is easy for you then that's your opinion, however I am sure that most people can agree that legendaries take some effort to get so they are more than deserving of their true stats.
In Singapore (where DragoniteSlayer and I are from), the average residential town (population 100k-200k, area ~10sqm) has one or two legendary raids per hour, with large crowds virtually guaranteed (at least in the first five minutes).
Without a nerf, Mewtwo, Slaking and Groundon would completely break the meta. There is a reason why most legendaries are banned from Smogon battles.
