Maybe change it so you can only choose a miniboss (maybe excluding dragon) only 3-5 rounds?
Can we not just leave minibosses alone? Its only a few people that complain about it, why not ask players in game what they think about this? We should not only be thinking about the opinions of common forum goers, but we should hear what non-forum users have to say.Lots of players don't even use the forums, when I go on and admin I get many questions from new players like "what is the boss battles gui?" or "Do I need it to play?" and then the occasional "I didn't even know there was a gui."
Now the one way I think we can fix that is by having someone ask questions to people in-game to see what they think boss battles needs, and then once we have a certain amount of opinions someone posts it on here, kind of like how admin apps are poster once they are reviewed.
Aslo I have the solution to all of the problems related to weapon spam and op-ness:
Invincibility Flashes, these are commonly used in many games and limit the amount of damage that can be done to you or your enemy. Usually invincibility flashes last 1 to 2 seconds, but can vary to up to even 3 to 5 seconds.
That would solve your weapon spam problems and it might even be so good that old weapons can be brought back(you know the ones that where deemed "game breaking").
Edit: I really hope I didn't cause a stuffstorm :|
