I can't enjoy the game changes that much at the moment because of the lag. It takes 5-6 seconds to register a single click. I hope this gets solved soon so I can give some proper feedback. That said, I like most of the changes made to the game. More levels and affection levels, item levels and stats, kobans for completing the dailies, legendary items, and so on.

I don't however like the fact even the higher trolls don't give exp.
Fighting the trolls instead of battling other players helped players to take part in different contests at the same time (gain xp, fight 'troll xxx' and get points, etc.), which in turn gave us chances to win kobans. Now we have to battle other players to win xp gaining contests and trolls to win the ones with points for fighting them. But both these use the same type of energy. This is an issue that needs to be fixed.
