Destiny was C average game it could turn into something better if Bungie steps up with their format. I'm looking forward how hard Bungie will suck from now on or if they can keep up with good relevant updates.
There should be space battles and at least use the transport ship for something. Crota's end was below average and the set of weapons are uninspiring in this endless grinder.
Bungie should allow more exploration expanding their bounding box on the stages, increase the AI tactical and military accuracy and diversify the races.
The Cabal was their best design. Would be interesting to have their heavy armor, better jet packing and strafe and heavy Gatling Gun.
The Fallen, Vex, and Cabal where good however the Hive sucked greatly. This game could turn out good if Bungie stops being so Bungie with their philosophy. They should expand the existing levels adding more detail and updates to a TRUE NEXT GENERATION game and stop looking at the PS3 and 360 antique museum boxes.
Would be great to see DLC that actually improves the game with better vehicles, graphics updates and weapons. They should tone down the insane grinding.
