Wow, what a great spot! Nailed almost all of the concerns people have been discussing, especially the special ammo! If they have time to change anything, I hope they differentiate the classes more. An easy way to do this would be to alter the weapon system kinda like mass effect 1.

Each class has a "specialized" weapon and abilities that support that weapon, such as increased accuracy, damage, etc. Titans use assault rifles best, hunters use snipers best, and warlocks use shotguns and fusion rifles best. Everybody gets a hand cannon as their secondary to balance out range and damage. Heavy weapons like machine gun and rocket launchers remain the same. Just this simple change would make a huge difference in requiring different classes for a balanced fireteam. In addition to this, each class ability should be more prevalent and more frequently available.

Also, I hope to see crafting in the full release.. And maybe an option to hide your helmet. Except when places that require one (like mass effect). And maybe dyes for armor? Maybe I'm getting too picky haha..

Still no mention of trading though...
