You should remove health globes and CD on Potions. And then make potions wich can boost players with, higher life leech, xtra speed, bonus damage, stuff like that would only make it more fun, even make items wich could higher the chances of potions like that dropping.
I dont like the idea that players are totaly addicted to health globes to do battle. Diablo is a ACTION RPG, not a MMORPG played from a sky cam, or an arkade game with extra loot....
