Hello, I've got 2 ideas as the title says.

The first one is a new duel option, with this feature you could duel against more than one person, and could duel like 2v2 or 3v3 etc style.

The second one is some target dummies that act like if they were players, so you can try out your mana drains on them, your cc abilities and some stuffs that only works on players, like dominator spells.

I hope you like my ideas
