Resurrect is hard to pull off, how so ? Is it harder to pull off than holding right click as Reinhardt or press e as Orisa.
Sure people might kill or CC you to stop it, but so does many other things in the game, when you try and use them. If its a pick off, you are usually guaranteed to easily get it ressed with no one in sight to deal with it, cause tanks is shielding you, sure you´re gonna die with high chance if you do it in a team fight and righfully so. It is a get to a dead body and press E, not hard to pull off.
Aiming isn´t the only skill related aspect she degrades, thats why i said “Since she would degrade every aspect of skill you might have”, if you want proof of this how come pro mercy players that played mercy 100% of the time in OWL, never ever picks her when practicing outside of OWL ? They play anything but her, unlike other specialists.
She has an easier time surviving cause of her passive heal that mind you is for some stupid reason 2 seconds faster to recharge than other self heal abilities like shields. She has one of the best mobility options in the game and on the shortest cooldown. Both of these lower her requirement for positioning and self awareness/game sense severely.
After this her beam is lock on and can never be broken unless a player leaves los for more than a second or is getting out of her range. This allows her to never have to deal with the awareness of worrying about Healing/Scouting/Damaging. Unlike other heroes that have to choose between either one, she can do pretty much all of them with one lock on and swapping between LMB or RMB as she sees fit. Another one, there are even more, but to deny these are completely mental, her not having to aim is just a whole other layer on top.
“That isn’t a good thing, this proves that Mercy is now useless (at higher ranks.)”
No it proves that people can´t get to a rank they dont belong to, unfairly solely because said hero was OP, lots of people play heroes and have touched Mercy and are top 500, Top 500 doesn´t really have any heroes that are top 500 OTP. Sure a some here and there but nothing compared to the sheer amount with mercy once.
This was because of the game being about swapping and being able to play multiple heroes/Classes of heroes. As soon as you had more than 1 mercy player, it was a problem.
And no, mercy is not useless at higher levels, unless you can actually play ana well, which requires an insane amount of skill, then mercy is still gonna be better for you in most cases of gm/top 500, which is how a hero is well designed. Cause mercy is such an easy to pick up and master hero.
