Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Well, too me there's more than that. Firstly I'm not the most experienced around here, so I don't know how much actually will change, and don't feel able to make an educated guess. Secondly I prefer a "don't worry, be happy" approach to this. Why be so negative when there's clear oppinions on it...
This. Try it out before complaining. If it's bad, get used to it, adapt or, if if it's too horrid, witch I doubt, stick with the DPP meta. If it's fine, then that's it. Let's wait with the complaining untill we get a chance too try it out.
A big change for sure. I'm not really sure what to think about it. Right now I don't feel like I would like it, but I'll have to try before I decide on anything. Even it's a "bad" change, I'll accept, adapt and get over it. Or stick with playing DPPt :D
Pinch-berries being used for more boosts seems interesting.
I wonder how the "infinitely" part works though. For instance, Harvesting a pinch-berry for a +6 boost (possibly in all stats with Starf Berry) in one turn doesn't seem probable. I could imagine it being once per turn or something like...
Or Sableye. Speaking of Sableye, what use is Stall? Who think it, or any abilities actually, will change in Gen V? (Bronzong being completely Heatproof anyone?)
