exeggutor question

I would stick to those two Pokemon that are maxed out. I don't have many opportunities to put 1 exeggutor in a gym, let alone 3. This might be different in your area.

I think Exeggutor needs confusion for defense. It is a pretty significant drop in defensive damage without confusion. Save your candy for your two Exeggutors with confusion.

As gym CP continues to creep higher, a 1600 Exeggutor might become more useful for prestige against Rhydon or Vaporeon.

If you regularly attack gyms with friends, E/Se might be a worthwhile investment for an attacker. Multibar moves are better in fights with more attackers.

I have a 100% with that moveset. I'm just shy of 2600. Would recommend. My area is loaded with Rhydons and water types. Very nice to toss Eggy between two Vaporeons.
