1- Wildlife with aggro management mechanics. Makes taking out world bosses or squads addictive when you can drag huge wildlife over and get them to fight for you (like Guildwars 2) 2- Have some replayable random generated area with unique weapon upgrades 3- for people who are not loot whores and have maybe 6 preferred weapons, let them be evolved like any of the hundred mobile RPG games on the market. I'd love to add the fire elemental component of an old Vex to my pistol or even add the invisibility mechanic from "Patience and Time" to my Atheons Epilogue. 4- Space battles? I don't know if this game is as dissapointing as the first with its lack of open world environments (TURN BACK! ....*Boom*) but taking off to space in our ships and upgrading them enough to reach other planets would be better than just reaching the next part of the story. 5- Don't make the amazing gameplay a 1 shot pony! Taken king intro misions were amazing.....and we had no reason to ever revisit them....that's a sin! 6- People pay £10 per month in Warcraft so they can solo old raids for loot using their upgraded armour and weapons. This mechanic alone is why i pay £10 per month for warcraft. I enjoy the power new gear gives me and I can see and feel how much easier it is to kill mobs in content initially far too difficult for me. 7- Becoming higher level and more powerful needs to feel like it in the open world....not like Destiny 1 where level 4 mobs kill you just as quickly at level 1 as they do at light level 400! 8- Advice - I know Bungie want to shake things up a bit and stamp their own version of how characters level etc but Bungie seem to only take tried and tested mechanics out and put in worse ones. Don't do that. If you're going to change things, make them better, not worse. 9- Don't make legendary weapons part of our stable line-up and then choose later to make them exotic. You did that already and every PVE player hates it...there's no reason for it and you made the game worse for it. 10- Let us assign 3 of coins, weapons Synths or anything in Destiny 2's equivalent to the "D-Pad". How many times has people died in the game due to the loooong loading screen to inventory in the middle of a fight to pop 3 of coins or more ammo? Many...yesterday I died twice in a row on the bond Brothers strike popping a 3 of coins between the 1st boss and the second....it's just a garbage mechanic that needs deleted. 11- Remove run cooldowns or indeed, make maximum throttle make you run. Who walks anywhere except Youtubers doing silly dances in the tower???? Plus, you have a piece of gear that removes run cooldown anyway so why even have a cooldown? Nobody gets it and the games worse for it. 12- Have competent game directors not use the current community as beta testers....So many issues went unresolved with Destiny 1 I think, due to the terrible game engine but that put many of us off and was an insult to the community.
