Yeah. Because it's totally impossible to be creative and just ditch the monster of the day staple they sticked to through 200 freakin episodes! There is a certain limit on how many variations you can pull off. I have yet to see an episode when they have to fight on multiple fronts, I'm at episode 71 11 minutes 53 seconds in and I have yet to see a demonic invasion of a proper scale above <max_number_of_current_heroes>. I have yet to see them discovering a chaos/evil cult trying to summon a demon for whatever nefarious purposes they have. I have yet to see aliens actually invading (I mean how in hell did Ali and Ann get away with that GIANT TREE?). mycetyc spore pods so numerous that they blot out the sky. I have yet to see any situation actually progressing beyond the sailor soldiers (and tux, and That Pink Spore). But are they... you know... soldiers? They don't seem to have a consistently strong level of combat skill, before the retarded techfest known as the rest of the seasons (starting with SM:Return) happens, but then things go off the scale (of reason) for no particular reason.
The best fight I have seen was Day of Destiny when the doom and gloom girls wiped the icy floor with the sailors. Just because it felt so real. It felt like what "SHOULD" have happened in all the other fights if the enemies actually grew some balls and decided to use their corrupted negabrains. I throughly enjoyed them using actual tactics, such as distraction first with the illusions, then focusing fire on the sailors, taking them out one by one, and if Beryl actually had that good villain pragmatism with her, and sent another batch of blood thirsty demons when Sailor Moon was alone, or even dropped her into the icy ocean (since she HAD control over her flight! she transported her into her negalair.) So when the combat was going on, I was actually cheering for the DD team, because they were so freaking awesome. But then plot armor kicks in, Rei pulls off a heroic sacrifice and finishes off another... duh.
Well, long things short, if they can simply ramp up the villains' efficency, and monster amount, they can give the other heroes more opportunities to shine. And even some actual tension.
