I just got done playing graffiti I like it but it is a little slow but I like the portal based game. I know that there is like a base layer of playing this game and the possibility to do so many cool things and get your gameplay up to another level by using the portals so I like it to get your mind working more on how to use the portals. I really like the same for takedown the need for speed really gets your mind working on how to be quick and traverse the map with portals. While I was playing I was also thinking it might be cool to introduce a ground slam with different abilities per class like you have to be a certain height in the air and hit crouch twice or something and you can slam and either like reveal enemies on the map or give your teammates a buff or obvisoly deal damage. I think some other melee heavy options would be fun like nunchucks that can hit very fast close range and maybe like a spear to close in distance more. Also an exploding bow and arrow like the torque bow from gears of war would be sick or sole something you can target an area and something drops from the sky like a laser or something
