They could also put in the Magneton line. I would be going for quests that had Electabuzz and Magnemite/Magneton for Gen 4. Ampharos isn't of much use, as Dragon Pulse is easily avoidable. While Focus Blast may be effective VS Rhydon, Groudon tanks it quite easily. Lantern isn't good. It's weak to Grass, and grass types resist all of its moves (A-Exeggcutor has double resistance) and since it doesnt have Waterfall, Groudon can still take it out quite easily, not to mention Rayquaza and Mewtwo...
Field research - Electric types
So with the next set os research forcusing on johto electric types...that only leaves 2 lines, mareep and chinchou, twchnically 4 including pichu and elekid, but those are baby evolutions that cant be encountered wild/research breakthroughs, so is almost every new research going to give out those 2 evolutionary lines?
I'd be glad if they did, ive got a dragon pulse amphie i've been wanting to power up and good defensive one I just dont have the candues for, plus lanturn's a good bulky water type for gyms
Answers
I am excited about it, I like ampharos and lanturn, both as pokemon in general and as defenders in gyms, I just find it odd that a whole month would have only 2 species of pokemon be the new research encounters from what the announcements suggests, I do agree with him that I hope magneton line's there, as magneton was made a steel type in gen 2, and elekid was added.
Sometimes the pokemon doesnt always need to be major league meta relevant, sometimes it good to just get a rare pokemon
The announcement says "Electric-type Pokemon and Pokemon originally discovered in the Johto region". Not "Electric-type Pokemon originally discovered in the Johto region".
Two themes, electric mons and Johto mons. Mareep and gen 2 starters seem likely and Pikachu probably stays no matter what. Magikarp and a ghost type (Gastly or Misdreavus) I think will also stay.
