Return of the Legends

Description
I got this idea when I was thinking on how I could remake my current map (found Here) while I thought about Orc Gladiators. So this map contains elements and ideas from both of them. The current idea go as following:

[B]1)[/B] There will be 2 teams and 1 arena. The teams will have a base on each side of the arena and there will be a barrier in the middle of the arena so the teams will be divided. This will be a custom hero map so it starts off with the players choosing their hero and his skills (3 normal + 1 ulti). When they all have chosen heroes they will get teleported to their base.

[B]2)[/B] The game will be based on rounds. For 3 rounds you will face creeps (like in orc gladiators). If you kill all creeps you have finished that round. However if you all get killed and creeps survive you will loose lives equal to the amount of creeps alive. Each team starts with 30 lives.

[B]3)[/B] After the creep rounds the barrier is broken and the two teams can fight each other. The fight will go on for 3 minutes (so players can re-spawn and come back to the fight etc.). If you are really successful in the fight you can fight your way into the enemy base and start attacking their main building. They loose and you gain 1 life for every 100 hp lost of the main building.

4)[/B] The team looses if they reach 0 lives or if their main building gets destroyed.
