I wasn't expecting them to show off EVERY aspect of the game in one stream. I believe that more stuff will be shown in the future and maybe even new stuff might be shown at E3. Personally, I liked the Titan super and it looked like the shield can be used to block projectiles (go figure) which got me thinking that the shield in crucible could possible block or reflect the supers of the enemy. I'll definitely wait for more updates for the game but as of right now, it got me interested.
