Yes, we've all had those matches where players constantly keep on typing instead of fighting but they are few and far between.

Without Feast chat, we cannot co-ordinate attacks, we cannot even give a simple detail that can end up winning the match; every Feast match is different, no matter how many phrases Square puts into it, there will still be frequent moments where you think "I wish I could say this".

The Feast is not better without chat, the Feast without chat is a free-for-all with no strategy.
