I wasn't trying to "explain" those ults so much as illustrate that DVA's is the only one that can be used essentially with zero risk as i see it. But you are correct i am new to game so if you'd like to explain so i can potentially understand better i won't complain. I would much rather learn and get better then just assume i know everything as i am well aware i don't.
Risk has nothing to do with it. None of them have "risk". They are Tanks, if they are doing their job then they're going to be in position to Ult.
You need to measure by effectiveness.
My ratings for most effective ultimates would be:
1) Rein / Zarya
3) Roadhog / Winston
5) Dva/Orisa
Obviously some debate here.
A Rein/Zarya Ult changes around games so much. Basically turning around teamfights or creating team wipes with much more frequency.
Road/Winston ults cause a lot of chaos because of the immobilizing & zoning combination their ults provide, and throwing people into pits of death if on the right map.
DVA/Orisa aren't often the leading cause of a team wipe imo, DVA could get lucky of course. Dva ult is good for zoning, but so are Winston/Hog.
I was fighting in a game the other day and we only had to defend this one last push to win, Unfortunately we did shit attacking so they only needed to get on the point for a few seconds for us to lose. The main enemy attack came from the left angle on the first point in "Hollywood". AS soon it began and most of my team reacted DVA tossed her self destruct mech from out of sight of anyone but coming in from the more normal choke point. It landed about 25km away from anyone maybe thinking we would have bastion and Mercy in that corner. Yet it still killed Mercy and Moiria, and knocked bastion to low enough hp meaning we wound up losing.
It's not like this is something i rarely see at my level (Mostly 2000s level players) either. hell it wasn't even aimed remotely well and it still worked in this case. The guy playing Moiria is a GM level (I think 4600 is gm?) support player playing on his alt account btw. Despite that I've seen him die to DVA's ult as much as any other ability at least.
Single-game examples don't prove anything. Dva can get lucky and catch someone out. But I also wonder if you're playing with sound off or don't know the map? There's plenty of hiding spots on Point A Hollywood and the Audio cues are pretty obvious and give ample time to hide.
Hollywood A has to be the easiest point to avoid DVA ult. You can simply duck behind the car lol. Not counting the multitude of hallways and buildings.
Did the Moira tell you he was GM? Unless he's your friend and you can prove it, then don't believe anyone.
But yes, it's not unfathomable to believe a GM player can be caught by a DVA ult, doesn't mean it's the Ult though, just means the guy either had no escape (odd as Moira) or wasn't paying attention (more common).
As i hinted by saying i would like her mobility nerfed i think that's the far bigger issue. As it stands it's not like DVA is a gamebreaking hero... but she is very strong and i wouldn't be shocked if she has enormous influence on the meta as long as she is in her current form as the better players exploit that mobility more and more.
DVA may be slightly OP but not because of Ult. You might have started playing late, but she use to never have rockets... those added a ton of damage to her kit. She can now zoom at squishies risk-free and blast them with rockets.
Somebody else mentioned mobility creep with moiria an it's def true it does seem to be dangerously infesting the game.
We have some original heroes that all have insane mobility. Tracer. Genji. & Winston.
And you have pseudo-insane mobility with Junkrat, Widowmaker, Pharah, Mercy
I think the complaint with Moira is that it's dangerous putting mobility on a healer, but we already have Lucio / Mercy
Like I said a few posts earlier, I don't see huge issues right now with any particular hero.
They seem to want do passes on heroes not seeing competitive play. Personally, it would go a long ways just fixing some bugs (ults disappearing on death & Line of Sight issues mainly.)
