>>50809029in XY its because it was just a no-frills battle tower and the game had little else to do. and then in ORAS it was just copy pasted over the battle tower/frontier from gen 3
the tower clones surrounding it at least had something unique to the,, in BW you could do the easy first round at an actually appropriate time with only 3 badges and the battle tree had the special bosses and scouting for multi battles.
