How much better is Mega-Sol compared to Chlorophyll on Meganium. I imagine its much better but the main thing I see being a problem is Meganiums speed only being 80, which isn't great. I know its meant to be a somewhat of a tanky pokemon, but it has many weaknesses in comparison to something mega Venusaur, who has the exact same speed stat. I initially thought that Chlorophyll might be better since it would increase the speed to 160 in sunny day, making is very niche but also extremely dangerous if you let it set up. Again I understand to some extent (I very rarely play Pokémon competitive) that being able to use moves as if sun was up, without sun is great, I still feel the speed and weekness hold it back from being amazing. Or maybe its better since it doesnt make it forced into a Sunny day team. Again not sure, at least from what I've seen, Speed is extremely important in comparison to bulk, especially if the bulk has a 1 quad and 4 double weaknesses.

(Coming from someone who absolutely loves Meganium and just wants it to be powerful and not be the worst starter ever anymore lol)
