When a game like Rainbow Six Siege X enters its testing period, players typically focus on things like balancing tweaks, Operator reworks, or map adjustments. Of course, this is to be expected with a game that has such a dedicated fan base, as any major moves like Siege X moving forward would need to be examined closely. However, Rainbow Six Siege X's most talked-about feedback wasn't about weapon stats or gadget synergy. Instead, it revolved around an unexpected aspect that caught the developers somewhat off guard.
