They're different now. Why so many players dont lvl there anymore?
Reason is simple: There are many better spawns now, Lvling electric on elders? pain in the ass, it's better to go on 100+ water. Leveling Water pokes? Go on 100+ fire, way better and safer. Lvling Rock pokemons? Go on 100+ fire too. THAT is the reason why hardly ever someone goes there.
If you weren't able to use protection agaisnt 3 elders - l2p because I was killing 5 elders using C trode, espeon, Blastoise and C buzz (sometimes helping to finish them with other pokes), while buzz is the only pokemon which may be hard to obtain at 100lvl, so please, don't tell me elders are too hard.
PS Elders aren't supposed to be easy spawn lol
