Here’s a recommendation for the Raid Tournaments that could reduce frustration and enhance the enjoyment of the game for all players.
For Raid Tournaments with Element restrictions, reduce the likelihood of the restricted element tile appearing on the board. While all players will have the same chances of a poor board and over the course of a 5-day tourney, each is likely to have 5 poor boards due to more restricted element tiles than average, some players may run up against this early in the tournament while others would hit this later and given the limit of 4 defeats this would favor those that have poor boards later.
Below are two of my first 5 boards day one of this week’s tournament - 4 Star Rush Attack with Dark Element Restriction. I had little to no choice but to activate the restricted element tiles and with the Rush Attack ended up not getting any points on either board. This generates unnecessary frustration for the player.
While this might reduce defenses effectiveness, the defense is spread out over all 5 days for every player, so it should equal out over time and as you do not see the boards, there is no frustration due to knowing that you were unlucky.
