Toxic Environment.

You think Pvp in FFXIV is Toxic?

Try playing League of Legends.

That'll show you what toxic really is.

I think player can be mad about reward also, loose too much make them away from the reward, but it's not a good reason.
I will certainly not get it, and everyone will not get it just the 100 first.
it's not a reason but nothing will stop some players to be toxic.
