Notes:

This can happen if you walk into the enemy's spawn – no super-nuke or rapid fire defense lasers like the other games. Just pushes you away. Enemies are also 100% untargetable and immune to damage in there (even by their own targeted spells, I think). It's only supposed to push you back a few steps in front of the stairs leading up to the enemy spawn.

I did this a while ago in the "Try" single-lane debug map that lets you level-up as much as you want, gives you access to all skill path upgrades, etc., with any hero in the shop for free as much as you like. It's f-----' smart. (They also let you buy skins for heroes you don't own so you can take advantage of sales until you get the hero and can still use it when they are on free week rotation.)

Random side-rant: "MOBA" is the worst term f------ ever for video games. Everybody stop using it to refer to games like Heroes of the Storm, League of Legends, Dota 2/DotA, etc. Call of Duty could qualify as a "Multiplayer Online Battle Arena" by its literal definition. Use the term ARTS – Action Real-Time Strategy.
