Was just wondering is there a certain evolution thats better than the others? I'm also unsure of whether umbreon/espeon is in this game, plus I definately don't need a fire type. Which evolution is considered best and what level should I evolve at? --- DBZ BT3 Friend code: 3308-3363-4229 Dragonball Z online name: Gompers
Generally, people don't seem to recommend Flareon anyway, so no worries there. Wouldn't matter who you chose though, just depends on which "type" you may want or need or whichever one you think looks the coolest....your choice. I went with Vaporeon because I didn't have a good Water Pokemon at that point and I already had an Elec type in Pikachu. However, Jolteon is very speedy and has great SAtk, so he is a very good choice if you want to go Elec. I don't think either one learns their elemental skill when you get them evolved, so you may need to give Vaporeon Water Pulse or Surf, when available and Jolteon Thunderbolt via TM/HM.
Umby and Espy aren't in FR/LG, so your choice is limited to those three until you get R/S/E. You should evolved them right away, no real reason not to. Just check Eevee's skillset in the Pokedex and see if he has a skill you want to keep that only he learns. Otherwise, pick a stone and enjoy your new evolution. :)
