Ideas like arenas and tournaments are a given. But we all know that it could become a "potion" race at one point - whoever has the most potions will last the longest. So here are two ideas to keep things interesting when/if tournaments are created:
1. Set a max level, for instance 100, so no Pokemon can be over that.
2. Introduce a potion/item cap.
An example would be something like "You can carry and use a maximum of 30 items during the whole tournament". This way you are sure no one would stock thousands of potions and just heal until the world ends. It also leaves room for strategies and creativity - someone may carry 30 healing potions, others may carry a combination of 15 healing, 10 reviving potions, 5 anti-paralyzing potions. This way the players are left to create their own strategy that is unique and isn't just "let me get 9000 health potions and the other guy will definitely give up at one point".
3. Timer to prevent AFK-ing. 'Nuff said.
Loving it so far, guys! Keep up the good work :) Now if I could only get a party of Charmander, Squirtle and Balbasaur... :D
EDIT: Added 3. Timer, after reading BigPlayK's post :)
