Let me briefly digress from the topic of past tournaments and talk about the future, specifically the fifth stage. Currently, patch 1.5 has been released, featuring a very important function: "battle recording." This means there will be no more questions like "who, how, and with what?" You can always ask for the battle log to be provided (although the number of saves will increase, but this is a small price to pay). This feature doesn't take up too much space (although I haven't recorded any particularly long battles yet, I just haven't gotten to that point).
So, if patch 2.2 with similar functions doesn't come out, the tournament for the fifth installment will be held on the original version.
