We (on PC) just recently got data that showed the most used troops. Mercy is right even with the stronger cards, but is not at the top, which implies that she can’t be THAT op. If she was so brokenly OP like you claim, more people would be using her than they are.
No one is making you have her on your team
P.S. I don’t have so much of a hidden agenda as much as I have an expectation for games to be close to 2 minutes. Max at 4. If the comp is interesting enough and intriguing to play, maxed at 5 minutes.
Any more time spent than 3-4 though, is not very optimal for your rewards… 2 is my preferred but I’m not so unreasonable that I don’t see others points that it’s an “easy” button. While I will argue that it is a good thing for the game to comply to all levels of plays I will not let that stomp over all my opinions. So, for your knowledge, my “agenda” is 2-4 minute game, which is not too much to ask for. You have a hidden agenda as well (don’t be hypocritical) Don’t assume otherwise next time
And, with that in mind, Mercy is not OP because she is not consistent. You only sometimes can spark her first. That is the single reason why I don’t find her OP. More often than not she is not going to go on the first turn, but this saves you from filling her up (very nice for a blue team where she’s on the bottom and color blocked) and when the board is good you can use her.
And counters actually are a fair thing to point out. If you are running against a manticore, as an example, he will drain Mercy’s mana on his turn (unless you run other empowered in your team), so if the match isn’t set up for you to smartly use her skill then you’re going to lose it, which negated her entire trait.
