Sounds cool.
With the capturing and protecting of bases, it sounds like Backyard Monsters way back in the day
Might want to install more than one bracket to make things as fair as possible.
Like this.
Levels 1 - 10 map (mythicals approved)
Levels 1 - 10 map (no mythicals)
Levels 11 - 20 map (mythicals approved)
Levels 11 - 20 map (no mythicals)
Levels 21 - 30 map (mythicals approved)
Levels 21 - 30 map (no mythicals)
Notice that its sorted by level instead of rank, to stop level 30 pros from dropping to rank 20 right before it starts to ensure a win in a bracket map.
If a player has chosen to be in a (non mythical) bracket map and tries to make a mech with a mythical on it, they will confronted with a message like the following, and won't be able to use that mech until the mythical is removed.
"Mech has a
Mythical Item! No Mythicals in this bracket map!"
This also stops cheating.
The top, say, 10 players in each bracket map get a reward for having the biggest base at the end of the tourney, size of reward varies on position.
If it ever gets put in, it probably should be a once per month thing. Not one per year!
Awesome idea!
