Sandbox/Practice Mode
I think that this would be a good idea to implement as a custom game mode, although it isn't really a 'mode' but rather additional options. This would help people test out builds, learn certain mechanics, and learn more about specific matchups without having to grind out a full game.
Options include, but are not limited to:
- Infinite gold or items with 0 gold cost (to buy certain items without having to spend X amount of time farming)
- Starting Level: Being able to choose which level you (and opponent(s)) start the game at. If you wanna skip ahead to level 6 or go straight to 18 (anywhere from 1 to 18), that's your choice.
- Objectives: Able to pick which objectives are up (turrets, inhibitors, dragon, baron, etc.) and which are down.
- Champion location: Ability to teleport/move champions to wherever you want. If you want to practice Baron fights, you can move everyone there. If you wanna see which locations a champion can jump/dash over/though, you don't have to run all over.
- Mana/Cooldown: Ability to eliminate or drastically reduce mana/energy costs and cooldowns for abilities (Like URF)
Obviously, there would be no IP/XP rewards for these 'games'. It's just something that, I personally, have been thinking about recently.
