Anyone else notice that mercy is just a must pick now? Maybe not at pro level she won't be, but every where else? Definitely.
I think we might be over-valuing small rez based on our experiences with Huge Rez. The new Rez is much, much riskier due to its shorter range and I think that will come into play. If you are very badly out of position when you die, Mercy won't be able to resurrect you without dying. We've been playing with Mercy 2.0 for about 24 hours in the live servers, so I think there will still be an adjustment period for a while yet.
A few situations that nullify the rez:
The new Mercy really rewards team play and team fighting instead of the current solo queue meta of individuals carrying and getting the initial picks.
Either the community as a whole adjusts (across more ranks because this gets increasingly harder the lower you go) or Mercy just breaks the game and they nerf the CD on her rez. I think 45-60 sec on the cooldown would be manageable, you'd be looking at about 1 rez per team fight instead of two, sometimes three if the groups time to kill is too high.
Sure you've raised Mercy's skill cap, but you've discouraged (once again) simply just being good at heroes with actual high skill caps. It's like when they implemented OP D.Va, you've essentially nerfed every Soldier, Mcree, and Ana player to make way for someone to hold right click. Remember when we saw Shadowburn and Shadder playing D.Va. That shouldn't happen.
Mercy has always been the counter to simply being good and now it's worsened because all good DPS players are negated by a rez on cool down unless they just kill the mercy or completely frag out. Which they will, but it's that much harder to carry.
And also we are going to see the Karivs and the Jehongs of the world playing Mercy because you still can't go without Lucio. Sure, I don't think it will be that drastic on pro play because Mercy is arguably easier to kill now but the idea remains. She is too strong in ladder to go without.
All this to appease less than 50% of the player base and mostly those under 2500 where you start to get players competent enough to play Ana and Zen.
Just let Ana and Zenyatta be better, why does Mercy have to be at the table?
What I got from that is that Mercy is too good right now. That has relatively little to do with the skill cap/floor but I understand the concern. Honestly I'd wait to see what the pros actually end up doing with her if that's the angle you're going to take.
She no longer stops mass wipes but is an extremely strong deterrent against initial picks so a different play style will probably be needed to deal with her if at all possible.
It's been two days since she came out, I feel like people are having their usual knee jerk reaction to any change Blizz makes and the ever present echo chamber is in full effect. Let's give it some time and see if she remains too strong.
Personally I feel like some tweaks would go a long way in making her more manageable, but you also don't want to render her entirely useless in all situations.
Edit: I think one of the issues is that Lucio is almost at must pick status for the most part. If he wasn't we might be able to see some crazy support combos and this situation might not be as much of an issue.
Honestly, besides what has been pointed out, killing a mercy in Valkyrie is so mentally grinding if it's a good player. Looking at the sky box for so long you open yourself to getting shot at so easily.
Hog is kinda back to a good place now though, which kinda mitigates this new Mercy frustration. But I really don't see Blizzard keeping her the way she is now.
