Why you may ask? Well, come on, me and many others have so many things to be excited for!
We literally are getting:
A fully fledged story mode
Hundreds of PVE missions to level up your hero’s abilities
New polished visuals
New mechanics
New heroes
New maps & gamemodes
New skin redesigns!
Sorry, I just wanted a reason to let out my energy. Good day.
cant wait either, only other game thats an arena hero shooter is paladins which i play once in a while for something different.
Also in the pve i want to mass rez, shield generator, armour packs and more fun abilities to return!
Even if they add 6 or maybe little more maps, i dont think thats hundreds missions, and yes missions are ment to be happening on existing maps for pvp as far as i remember.
Doubt they even finish one story, and doubt even more its even 100 missions, unless you mean how many times you going to have repeat them to lvl up one hero (because grind need to be addes somehow)
A lot of cancer heroes are being redesigned too! 
The PvE seems very Borderlands-y to me,which should be fun.
Don’t forget the amount of new workshop gamemodes once the PVE maps, enemy npcs, and hero talents eventually get integrated post-launch.
yay and some of our loved heros are gonna become useless 
I’m so excited 
Not gonna lie, I’ve watched the Blizzconline and PvE streams a few times.
Hype level is high.
Yay <3.
I’m so excited for another generic hero shooter, with very little extra mechanics for heroes to play around with. Tightened control that fits to an eSports narrative.
At least pve lovers rejoice.
inb4 redesign is just 5 buffs with 1 compensation nerf
And it turns out that Bob only was a clever disguise for lvl 3 who never actually left us 
I’m excited for PvE and all the technical improvements, especially for new game audio! Maybe even support for true 3d audio, who knows.
more pepegas, so we can actually smurf, not playing gm game in plat
Then y’all enjoy buying it. I know I won’t.
I play the OW1 archives missions so much that I know where every enemy spawn is. I just need a few of the sprays and im done
I think I have spent over 200hrs on archives
SO THAT SHOWS HOW MUCH IM GONNA LOVE OW2
Winning archives legendary is SOO satisfying. Especially when you’ve grouped up with others trying for the achievement, fail multiple times but once you get it, everyone gets the spray and for me personally we all added each other in case new hard PvE achievements are added.
Now we know Overwatch 2 will be all I just said but enhanced, upgraded and kept permanently in the game… I’m pre-ordering collector’s edition.
Ppl were excited about Reforged too but we all know how that one went 
How much are they paying you and where do I apply, OP?
Yea, i not they removing big stun so no longer a anti dive/flank support not going to play respawn simulator for flankers/snipers…
Get ready for it maps that are already in the game with dozens of waves of bots over and over, but the actual story is gonna be in chapters DLC post-launch.
By “hundreds” you mean 20-30 with different modifiers like difficulty. And yay, grinding to level up your skill tree. You should get all skills for a hero after 4-5 missions so you can actually go have fun experiment with different stuff, but it’s probably gonna be a grindfest.
Which is all that could be in the game right now. And even better, all this won’t require you to buy OW2. It’s gonna be free for everyone who has just “OW1”.
Where I’ve not seen one that was any kind of interesting. Rein looks fine in the artwork, but in-game he gets a huge Santa beard. Bastion gets a hat, Genji gets a hoodie. Mercy, Winston, Tracer hardly change and Lucio is possitively ugly with his neon-noodle hair. There better be option to run “OW1” default skins or skins you unlock in PvP.
