After playing the beta, I have a renewed appreciation for Destiny 1. The beta for D2 felt like a major downgrade.
Movement was sluggish, and ironically, lowering the Mobility stat makes your jump faster.
The abilities are all weak, [i]and[/i] take an absurdly long time to charge. It should have been one or the other, not both. Whoever was in charge of that illogical decision deserves 20 slaps, fronthand and backhand.
This ties into the above paragraph, but Dawnblade and Gunslinger's Supers and abilities are incredibly underwhelming. The damage output and duration for both Golden Gun and Daybrake are far too small, and the ridiculous downward curve of the Daybrake projectiles makes it pointless to use in the air unless you're almost right above the enemy.
The Winged Sun perk on Dawnblade is broken. While it allows you to throw Grenades, and fire your weapon, while Gliding, hitting anything with your gun while Gliding is almost impossible. The weapon accuracy and hit detection drop significantly. In turn, it also makes the Heat Rises perk--which grants Grenade and melee energy on airborne kills--useless. Would it have killed them to add in an Icarus effect to Winged Sun? Geez.
Guns feel weak, for the most part, in both PvE and PvP. Especially the scout rifle, submachine gun, and Grenade Launcher.
Going back to Destiny 1 was refreshing. Abilities charge fast, and are reliably lethal when you need them, but weapons were strong enough that you don't need to rely on your abilities all that much.
At this point, Destiny 1 seems more enticing. They're gonna have to step their game up with the full game of Destiny 2. It's gonna need massive improvements if they want more players onboard.
