You missed the point of my asking that.
If it's a matter of looking at the numbers alone, all PvE content has higher numbers of players than PvP, both good and bad. I said this. Thus, why then would a chat restriction not be considered for what's effectively a larger sampling of negative players?
As far as dealing with chat spam, that's effectively worse purely because it makes a sound each time.
That's a bit harder to ignore than someone simply going on saying negative things. Not only that, I've said this plenty of times and if anyone's not clear on it, please take heed now: Most players want to win more than they want to harass or insult others.
And the playerbase has grown because:
1. Finally lifting GC restrictions improved matchmaking, which made queues faster, thus people weren't as discouraged to not even queue considering 1.5 hr wait times dropped to 5-10 minutes at prime times.
2. The cost and awarding of Wolf Marks was adjusted to make both getting Marks and buying items with them far easier, just in time for the event.
3. The Garo event was designed so that the rewards were only available from PvP FIRST. And in the case of the mounts, ONLY from PvP. If people wanted them enough, they made the effort to at least try for it, and they weren't so difficult to get at that point (See #2)
4. People FINALLY tried PvP and realized it wasn't so bad or as toxic as what they'd previously heard. Some even grew to like it and now play regularly. And even THEY feel the chat restriction is a bad idea.
You're attempting to back up his statement based on feedback, but have you not seen the nearly year old, over-90 pages long thread of mostly negative feedback about chat? Claiming the increase in activity was attributed to the chat restriction is simply skewing the facts to support a narrative that is entirely wrong and ignorant of several other important factors. It's like saying a job is perfect or perfectly balanced because of the number of people playing it (i.e. SCH and DRK in the Feast currently). With no disrespect intended, you may want to read into things a bit more before trying to support skewed facts.
Why is this a perfectly acceptable system to implement for RMTs and the like, but not for a competitive gaming mode? Especially when the RMT reporting system also warns you about false reporting, so no one can claim ignorance on that. As far as people abusing chat in PvP, first, I need to say this:
1. There's nothing wrong with being new. But if you ARE going to try it, try to learn what you can to prepare before you actually step in. Ignorance or lack of understanding is largely what leads to losing.
2. Don't become defiant or nasty when given advice. Consider that - IF the player isn't already being mean about it - they ARE trying to help. A lot of these cases of "toxicity" are often a matter of the "victim" shooting first. And no, I don't say this without having seen it happen myself.
3. As far as dealing with actual cases of toxic players who just dump on or harass others: Pull the weeds, don't ruin the whole garden.
