I'm a curious kinda guy, so I'll bite. What's your rank and how many games you got? Helps set the foundation for understanding your point of view in a way.
After the announcement, the PVP games in dia/crystal are pretty quite (at least in Elemental). No one marks, or calls out as much as before. Its more of do on your own and yolo. Amazing Yoshi P, you somehow killed the game.
So what does Yoshi P have to do with this? Should Yoshi P write "You have to mark targets and do call outs" into TOS? It is the community's job to create the standard way to do things like people did with Feast that didn't have chat and required way more teamwork to kill 1 person even once :p
Simple, a lot of players where afraid to chat cause they don't want to be banned. It's funny that most players reacted this way because they just have to avoid spamming but no, most opted to not chat and the problem with it is coordinated game-play is gone. Again I say this on Elemental Dia/Crystal rank. I noticed this a few days after the patch.
I played Feast, I know what you mean but don't lie if you don't see the effect of the announcement on the games. Well maybe in Shiva there was no change at all, lucky for you I guess.
I'd say most of the jobs are pretty well balanced. Its only certain kits that are overtuned and certain LB's that are too much of a game changer.
You're not going to be banned for using the quick chat and marking players. I'm still using my "attacking player" macro that prompts the quick chat and marks the player with no issues. If you actually read the update they are talking about people excessively spamming the quick chat with things like "Nice job!" when people are losing. Its obvious when quick chat is used in a toxic manner and when in an appropriate manner.
Yoshi P is a revered and respected man and he didn't make the announcement but he does oversee most of the things as he has claimed.
When their main focus is carebear behaviours instead of having an open discussion on the state of pvp and competitive I would think it would dampen the spirits and remove the motivation of quite a few.
And I'm too many years into playing MMOs to believe that.
