Here is my long and possibly 'Not gonna happen' BS list of things that maybe some other people wanna see, but most likely never will.
*Clears Throat...Ahem*
~No more minerals (I'm tired of spending time searching dead planets for useless material to upgrade weapons and equipment)
~No more upgrades (Useless mineral collecting to upgrade equipment for no real benefit for those who prefer to just dish out death without them)
~Varied Genders (Lets see females of the various races)
~Varied Ages (I wanna see Turian kids, Asari Kids, Krogan Kids, Drell Kids, and EVERY age group of EVERY race. Cause I'm sure the Universe isn't filled 100% with adults standing around)
~Living World (Would it hurt to have some people walking around? Or even events or actions happening more often? I'd like to at least break up a argument or deal with a pickpocket instead of walking around in a stationary world for 30+ minutes)
~Less Scripted Battles (When I can walk in a room and position my entire team in the perfect spots to end the fight in under 1 minute because I've fought the battle before...something is wrong. I'd like to see maybe some random instances in the game, some bandits just deciding to attack as you enter the cargo bay, or a violent fight goin down between soldiers and bandits as I enter the marketplace. It gets boring KNOWING exactly when fighting is going to go down, and that 99% of the time no fights will happen unless in a mission)
~Less 100% Combat Missions (If I'm a Paragon and I like to talk my way out of conflict, LET ME. It gets redundant to simply walk into a area and gun down EVERYONE with no discretion untill a cutscene appears. Maybe give the option to force people to surrender or flee through dialogue or sneaking up on them suddenly. Maybe some Diplomatic missions? Ones where you get to use your wit or correct dialogue choices to avoid conflict or open up new missions or events?)
~Wounded/Surrendering Enemies (If I shoot someone in the gun hand, or drop them to their knees, give me the chance to be Paragon and let them surrender or end the fighting because they can't fight back. Or give me Renegade options to kill a unarmed or fleeing enemy)
~Moral (If I'm under heavy fire and I'm running low on ammo, maybe my teammates should be panicking and getting negative bonuses such as accuracy or health penalties. And when I start to crush a assault squad or take down a huge mech, then my Team should be getting some buffs to health or accuracy)
~Better Cover System (The sticky and sometimes useless AI makes taking cover difficult. I'd like to be able to have my teammates take cover in more advantageous positions instead of hiding behind the most exposed crate their standing next to. Maybe also add some more flare to Sprinting to cover, maybe be able to vault over certain cover while sprinting? Or more stylish slides?)
~More Skill Variety/Cool Stuff (Biotics throw stuff, Techs hack stuff, Soldiers shoot stuff, but where are my abilities to perform a execution move or a stylish attack that kills a enemy in slo-mo. Add some skills that are even just visual and serve no advantage, maybe a 360 Spin where you spray gunfire in slo-mo, or a move where you vault over your current cover and are able to slo-mo shoot during mid vault? Plus many people would prolly like to see more Abilities for the Soldier aside from 'Concussion, or 'Temp/Useless Slo-Mo', maybe toss in a fragmentation grenade or a smoke grenade. Even a simple explosive round wouldn't hurt)
~Less Loading (I don't want to have to wait 5 minutes just so I can talk to my Teammate on the Crew Quarters because I'm on the bridge. Maybe have ALL teammates and necessary crew in a single area, or atleast have some sort of way to communicate over long distance so I don't need to travel there in person between loading screens)
~Less Bitching (My crew does nothing but complain or brush me off unless I do a 40 minute mission to gain their loyalty after spending 80min recruiting their arse. Maybe some more appreciation or the ability to gain loyalty without long boring missions for all 8 or so people)
