@goldfish I'm one of those people who do all that; I pretype responses, am a fast typist and I read quickly. However it doesn't matter that much when it comes to playing with others; being a slow poser isn't an issue - being a sloppy or inconsiderate one is.
In other words take your time. If I have to wait 10 minutes (or sometimes more) to get a pose I'm more than fine with it as long as it's worth reading in the end. Cranking out my poses faster than that isn't supposed to signal others that they need to do the same.
You don't have to change your posing style to accommodate others. Now if it's only for your own convenience, making sure you don't miss important things or name-drops in others' poses then sure, that's something... but there shouldn't ever be external or even perceived pressure to alter how you do things if you'd rather not.
Plus frankly any scene with 6+ people in it will be a scrolling, spammy nightmare for most people. It comes with the territory.
