Now that hype for new Support champion has died a little bit i think that we need to talk about her spot in the game, her healing output and potential issues.
I will not talk about her DMG, her escape, Luna... etc. I am focusing on healing because she is a Support champion. And imo. that's where she is lacking.
First of all her resource is just not good enough. You barely have enough resources to fully heal one tank and then you need to retreat and wait for it to fill up. Just imagine how bad this can get when Cauterize lvl 2 or 3 kicks in.
2nd thing is, you can only focus on one teammate while healing. Seris which is the most similar healer has an ability to heal for 30% teammates around the one you are healing. And that's in her base kit. With Io, you can only heal one teammate at time and then wait for 1 sec. cooldown just to be able to heal other teammate.
3rd issue is line of sight when healing. Again i will mention Seris. With her you just need to start healing your teammate and connect and then you can literally move away 3 walls between them and you and she never stops healing. With Io you can only move a little bit and you can't break line of sight, if you do that and try to hide behind the wall healing immediately disconnects so you need to be constantly exposed to the enemy team while trying to heal your teammates.
Don't get me wrong. I know that it's still early for this. But imo. these issues should be addressed because i feel like if she goes live like she is in PTS rn. she just won't be a good pick. Please don't trust YouTubers that are trying to hype you up and make you believe that "sHe iS sO OP!" no, she is not. She actually has few serious issues.
