I must be the last dope to have worked this out... by the time I stopped using in game chat I noticed nobody else was either.
Presently if I so much as say 'left please' or 'right please' or 'shoot the red tanks ******!' (my personal catchphrase) I go into a ping spiral of over 300. if you platoon chat the game is over.
The game is sometimes jerky without doing this, on 'mines' map especially. It is so bad my t54 can barely stay ontop of that big hill. Smoke was always an issue. Being near an exploding tank puts me into 3 frames a second.
Please fix this issue, the chat was good before 2.4. I do not care for the layout of the chat divided by clan, friends and global- when I get a message alert it can take forever to find it. I think friends and clan should be together.
