Cap level dummy furnishings are useless to players working out how to play a job they just unlocked. A cap level dummy furnishing can't be used as the one single dummy in a free company yard or a personal yard for a player who doesn't have everything at cap, because any target that is higher than the player's current job level has a miss chance which will prevent players from executing their job mechanics properly.
Please stop making dummy furnishings high level and forcing us to decide between using multiple furnishing slots on dummies of different levels or telling low level players they can't use the dummy because we like how the higher level one looks better.
All dummy furnishings should just be Lv1 so that all free company members or solo house owners can use them regardless of job levels.
