So I have been thinking this through on every detail. First off it would be either before halo reach so there would be spartans and a war with the covi still. This is because there would need to be spartans… So classes there could be many classes and obviously races. You’d have two factions the unsc and the covenant. unsc, would have humans and hired covenant rebels I.E. you could be an elite, grunt, hunter, and a jackle… Not a brute I figure that would be a covenant only race. And for there gear you could add mods that would add suit abilities like an over shield dps boost, agro boost so on and so fourth… On a side note I don’t see why other races couldn’t be made up… Now for classes…
You’d have your basic dps such as… Different variants of spatters like a ranged sniper class, upclose shot gun class mid rang assault rifle class and a stealthy rougey type sword knife class… Also you could have marine classes as well with the same ideas but they would have to be some what different… And for the elites… They would be close to spartans… The grunts would be tech geeks and be all about explosives id say they’d be like goblins from that one games I shouldn’t mention…
Now for the tanks… Well the obvious… spartans and elites… But then you could have jackle tanks with a light armor and there tanking is based on protection spells and there shield… And I would love to pve and pvp as a hunter… And brutes would have a good tanking class with the ability to rage and lost of battle cry types of concepts…
Healers… Would be marines and jackles and elites… Marines and elites being physical heals like stims and different med equipment… The jackles would be more like caster healers…
There could be raids and instances and small 8v8 and 16v16… Then huge battles of 40v40 with games of capture the flag grif ball all the good stuff…
You could have your own customizable ship and planetary travel…
As for the story I haven’t thought too much about that…
So this is my basic ideas for a halo mmorpg
