What i want in halo wars 2!

Im am a vetern of halo wars. I loved the game and all it had to offer. But there was always things me and my friends wished were different. One example is the playable teams. You could only decide from UNSC or covenant. if the flood or forrunners are going to be featured in the story and multiplayer maps, we should be able to play them. Another thing i think should be added into halo wars 2 is diffrent types of marines/soldiers. For the marines you could upgrade them and they would have diffrent things here and there but you would never feel like you had an army of diffrent and special soldiers. What i propose is that marines have bits and peices of custom armor to make it feel like you dont have a clone army. But what im saying is not put sparten armor on them and have them look like master chief or noble team. Add small details to the marines that players can notice but have those details be random on the marines when they are made. It could be a small red strip on their armor in certin places that makes the player feel like the soldiers would be able to custamize their armor to exspress their personality. Another thing is have a larger selection of marines or other units. The flame throwers where a cool unit to take down grunt hords or other marines but what if you could custamize (at a very small level) weather or not they be a sniper team or an explosives team. Also have this for the other units as well like warthogs and tanks. Another cool aspect would to have emblems on vehicals so if the scorpion tanks are rolling out of the base you can notice an emblem design on their turrent or track pecies. One last thing i think should be added into the game is deployable barriers or barricades to defend choke points or flanks. Add like a special ability from the ship or hero unit to add a barricade or barricades to defend off the main assult or flanking manover. Of course these would be destructable and you could only use a small amount of them. So for the covenet add those thripple barriers that are hard to destroy off of halo reach and for the unsc add like the concreat barriers and the metal ones. And you can also place units on these barriers to fight off the enemy units. And last but not least if we the players can play as the flood make it limited for us to use. Dont make it like playing as the UNSC or covenet. Make it so the player has to be aggressive and use fallen enemies to fill up the ranks of your army. Thats all i have to offer for what i think should be added into halo wars 2 thank you for your time in reading this hope to see these features or features similar to this in the furture.
