I have an idea. It would be a kinda AOS map but not the usual DOTA type. If you guys played Cabal Online before, the Nation War is what I'm referring to.
In this case, it would be a 6v6 situation if possible.
When you start the game, you can choose from 6 different heroes (or more if subjected to changes). Every player will have a definite amount of gold. They can be used to buy HP potions and Tower items. Throughout the entire game, you will not need to earn gold to buy better equipment because there will be no equipment involved. There will be sufficient gold given to all players, such that at times when you run out of HP potions or towers, you can buy them via a hotkey/item/skillbook. As long as you have a "Tower Item" bought from the shop, you can build one of the different towers available under the hotkey/item/skillbook, e.g. Tower that adds atk to surrounding allies, Tower that reduces def to surrounding enemies, etc. HP Potions will have a definite amount (e.g. recover 5,000 HP with 10 second cooldown)
There is no need for MP pots because all players will have almost full MP at all times with high MP regeneration, regardless whether they are spamming the usage of skills or not. This will allow players to use all their available skills.
When you just start into the game, you have about 1 - 2 minute to buy the items you need in a base. Both sides will have their individual base. The players will be automatically teleported into the Battle Arena when the time is up.
There will be various Guardians (hostile to all players) situated around the entire map, where players will attempt to kill it to make it friendly to their allies. The enemies will on the other hand attempt to kill the taken-over Guardians to make them their own, and vice versa.
There will be a main Fortress Base for each side, however, destroying the base will not grant you victory unless your team manages to destroy ALL the Guardians/Fortress Bases and make them your own. For e.g. Upon claiming the 2 different fortresses will not end the game. Different points will be given to the team members when they managed to kill the enemy players, the guardians and the enemy fortress. Points will also be given for building towers.
Every hero will have one (or two) skillbook(s) with up to 11 skills, 1 self-only stat buff (with a long cooldown), and 1 Change-Form skill (with a long cooldown). Every hero will have movement skills (dash blink fadestep), knockdown/knockback skills % chance, range/melee nukes (subjected to different hero). There will be no levelling system as you start with all the skills/buffs available. PS: I can elaborate more on this if required.
Upon reading all of these, if you are interested, feel free to contact me for more clarification on the ideas.
