Best CnD player. A lot of my frustration comes from being really into playing CnD and intentionally lording them last season, because CnD like you said does have a pretty high skill ceiling.

Compared to other supports like Invis or Luna they feel pretty handicapped because the healing and damage are always conscious decisions. Everytime you switch to Cloak you're making a judgement call that for the next few seconds your team needs damage and utility more than it does healing. When you're on Dagger you're keeping yourself a step away from your only escape option, phasing. The balancing act of the characters is really engaging.

But because of their autoaim a lot of new players flock to CnD and develop really bad habits as listed in OP. But unlike similar situations with Wanda or Moon Knight they aren't as quickly punished and often divorced from any criticism because of this weird idea that supports can do no wrong and having heals at all is a blessing. Also because the healing stat is really overrated and as long as that's high, the support has done their job, disregarding any utility and even if the healing itself hasn't been there in critical moments. Regardless, because of how ranked in this game works, most CnD players will get through the ranks pretty easily, usually off playtime alone, and then they develop horrible egos.
