You're not wrong on a lot of things here.
And the rest is opinion which can't be wrong. xD
Personally, I enjoy the mish-mash of playstyles n whatnot.
I've been a fan of Borderlands/Battleborn, and I've sunk an embarrassing amount of time into League of Legends.
Overwatch feels like a combination of both to me.
Most people are comparing it to TF2, which I've admittedly never played, but the whole "capture the point/escort" is really the only aspect of play left, which comes in pretty much any PvP games/modes.
Guild Wars 2, for example.
Borderlands/Battleborn really covers the whole "ultimate" thing, as well as the whole sort of futuristic feel and look.
And I'd suppose the short skillsets and whatnot (and also the "ultimate") also borrows from LoL and Dota.
For some people, I could see it being a bit too much, a bit too messy and unpredictable.
I feel like maybe if I didn't have my same playstyle, maybe I would feel the same way.
I'm not one to ragefit if I die, since I accept that as part of playing games like this. However, my priorities when I play Overwatch are: stay alive > capture/hold objective > make kills
The problem is that this is not how everyone plays.
If you are the type to go in guns blazing and the only thing that really matters is kills (or even just prioritizing objects first), you might die more often to a lot of the skills or ultimates that seem more bs than they should be allowed.
A lot of the game is not about the more head on combat that you'd find in LoL or Dota, or even Blands/Battleborn.
Those games are balanced in a way that allows for vs fights, usually characters have the ability to heal themselves somehow, etc.
Overwatch is not like that.
There are a lot of characters that cannot heal themselves.
You're left with depending on whoever is playing support, which cannot always help you, especially if you play sniper, a lot like I do. Which results in having to make a choice. Search around the map for health packs, or just commit suicide and respawn? Sometimes that is actually faster and the better option.
Certain characters will almost ALWAYS die in a head on VS fight.
Widowmaker, for example. She's a very squishy sniper. If you are face to face with her, scoping is impractical, and she does the most damage after scoping for a few seconds (since it has a "charge" mechanism). You would never scope face to face, so it forces you to use the assault rifle version of her gun, which doesn't do a lot of damage. It's very easy to deplete her 200 HP, assuming she's not already been hit once, which would then put her around 160.
The problem that I have with the game right now is that it seems VERY unbalanced.
"Picking Bastion" is a joke inside the community. You can wipe the entire opposing team using his machine gun.
(Though he's surprisingly easy to kill as a sniper.)
The community itself seems to have some issues sussing out these imbalances as well, providing suggestions to Blizzard that don't seem optimal.
Most of the community seems to want Widowmaker nerfed, and I've stated above that she's actually pretty weak, I find. And I have sunk most of my playtime into her.
I can see her scoped bodyshots maybe being nerfed a bit, since 2 of those would kill most characters.
But in every other aspect she falls short. As I said in my above post, when compared to Hanzo, it doesn't make much sense to pick her over him.
I enjoy the chaos, it feels so much more rewarding when you can make a quintuple kill streak despite the impossible odds.
But I get that it's really not for everyone, especially as unbalanced as it is right now. And if Blizzard follows through with the more "popular" suggestions of nerfing characters just because people are butthurt about getting killed by them, it may remain unbalanced for quite some time.
The lack of a story mode is also kind of surprising. I essentially paid $60 for gameplay I could get for free in LoL, just in a FPS/Borderlands/Battleborn coat of paint, plus some character skins. Not sure it's going to be "worth it" for everyone who paid that price.
My suggestion to people who are on the fence or who didn't enjoy the beta too much would be to just give it some time, but definitely revisit later.
Edit:
Nice.
