(Note: relative newcomer to the CAP process (was around for necturna))
Honestly? I didn't mind the Drought Wars as much. Yes it was very heated and split the community in two, but does that mean it was the worst thing ever? We had people fiercely debating how certain changes would impact the meta, and which one would be the most valuable in terms of testing out. It also highlights just HOW important weather is in Pokemon, since the other alternatives, Storm Drain and Water Absorb, were hardly mentioned as it became a debate over one ability that automatically provided one type of weather and an ability that made it strong in one weather type, but far less effective in another.
Now it was fairly caustic, and that part should be avoided in the future for sure, but a good debate like that was fairly good for the process, IMO.
I think we came up with a nice Pokemon that has a very interesting role that WILL have a big impact on the Meta. Between the stats, move pool, and ability, we can see how Rain, current king of weather, would hold up in the face if this versatile little chap, when teams could carry him just for a check to rain. (but sand would pulverize him, and sunlight has the potential to neuter him.) We know he will force rain to adapt to him, but how will he hold up to play when it isn't raining? That question will determine how successful this CAP is. If it can find homes on many non-rain teams due to being effective all the time, then success. If it is only seen on rain teams, then we at least learn that a pokemon's ability can trump typing when it comes to weather team viability... Or at least rain viability.
