As for quick chat, it's actually objectively better than the normal chat for sure because quick phrases at a press of one button is much more efficient, granted strategies can't be communicated and you can't correct people as the match is going on so they adjust immediately but all in all that's what the PvP discords are for, the community is small to begin with so that's not really an issue. Quick chat also did help the toxicity issue for sure, with this community being particularly more sensitive so derogatory connotative use of the phrases is at least healthier.
