Hadn't thought of Ice Spear locking your opponents. You could kill all 3 relatively easily that way.
Also, if you were the "Boss" you could just use Thunder or Crash Shot while immobile, since that is allowed in the rules stated. That would likely deal with your enemies fairly quickly too. Or since Alchemy is allowed, Golems.
I do like the idea though; but it would need some heavy restrictions to prevent cheesy wins.
Thanks for the suggestions. However, I still want to try with all of those allowed. I'm picturing the boss getting absolutely thrashed having no way to defend without melee skills. I hoping that pets can help to alleviate this problem by helping you get out of a 5-charge boss Thunder. I also want to avoid having a boss that just stands there. Being both immobile and useless at the same time.
As I mentioned earlier, part of early game is making a decision that will put the battle in your favour. Whether it's to turtle your boss or rush at theirs or distract the enemy team by sending one team mate into their boss. I want all these possibilities to be available before we add tons and tons of restrictions.
More importantly I want us to have fun with this. The only way we can do that is by having little to no restrictions and more communication and cooperation. That's probably the main reason why I want this to succeed. I just want to make the game fun again, if not, more fun!
