History YMMV / TheBattleCats

** If a player has extra space and is using a lineup that doesn't depend on "heavy" units, chances are they'll be using the Bony Bone + Biohazard Cat Combos, which due to their overlap provide two Research Up (Sm) buffs with only three slots, which is remarkably efficient for its cost. It shaves about 2 seconds off of recharge time, which doesn't sound like a lot, but can be a godsend when you need to field a lot of units in a short time.

** You'll have a tough time finding fans who have anything positive to say about Behemoth Stone farming. On paper, the concept is nice: Behemoth Culling stages (Hidden Forest of Gapra, Ashvini Desert, and Jinfore Volcano) appear at select times each day, and you can play them to get Behemoth Stones and hatch the Ancient Eggs. The problem is that getting the stones this way is entirely too slow. Even if you check in for all 3 stages each day, which might not be possible, you're still only getting 3 stones maximum -- most likely of the common purple and red ones -- when many of the eggs take dozens of stones of different colors to hatch. You can get additional stones by playing the Hunter's Map enigma stages, but this is a LuckBasedMission, since they only have a 50% chance of dropping when you get an enigma stage. This all adds up to a lot of time spent playing the same few stages, well past the point when they become monotonous.

* ScrappyWeapon: The Waterblast cannon for the Cat Base tends to go unused by the vast majority of players. It's an anti-Metal cannon which fires a blast of salt water, damaging Metal enemies by [[PercentDamageAttack a percentage of their current HP]] -- starting at 11% at level 1, and going up to a whopping 45% by level 30. The problem? Two words: CripplingOverspecialization. Base materials and helpers are often in short supply, and players will want to invest in other cannons with wider usage, like Iron Wall, Thunderbolt, and Holy Blast, before they even consider a cannon that only works on Metal enemies. Metals also aren't exactly in need of such a powerful weapon to be bearable, since there are plenty of strong non-uber options for damaging them and applying status effects, so it's also far less useful than the similarly-specialized Holy Blast. By the time a Waterblast is done charging, your critical hitters have likely already done far more damage to enemy Metals than the cannon would have, especially considering that most Metal enemies tend to not have a lot of health to begin with - even 45% of a lategame Metal's maximum HP will be only a few hundred to a few thousand HP that can easily be dealt in a few critical hits, with it only doing competitive damage to buffed Sir Metal Seals or the Metal Cyclone. The base's style is useful, giving resistance to surge attacks, but players will tend to avoid the actual cannon.

** Superfeline becomes unlocked after Cats of the Cosmos 3, and on paper serves as an easily accessible anti-Relic to prepare you for Uncanny Legends or any Relic stages you'll be fighting from that point on. However, it's a Normal Cat, which caps its level at 20 and drastically lowers its base stats since Normals get most of their power from Cat Capsule duplicates, which normally isn't much of a problem since you can fairly easily accumulate them. The problem is that for some reason, Superfeline's plus-levels only cap at 9 initially, and to raise it any higher, you need to get to User Rank '''10,001''', which still only increases the cap to +30; it can only be upgraded to the normal +90 at UR ''16,000'', and unlike other Normal cats, it only unlocks its True Form at ''20+80'' instead of 20+10, which not only leaves Superfeline heavily underpowered for the vast majority of the game, but [[ArsonMurderAndJaywalking clogs up your Cat Storage]]. Needless to say, by the time you reach that high of a User Rank, it's probable that you've either obtained several stronger anti-Relics to solve your Relic problems (including free ones like UL Legends or Idi:N2), or have just outright cleared Uncanny Legends, leaving comparatively nothing to use Superfeline on; and given Superfeline's abysmal base stats and costing ''999,999 XP per level'', you'd be lucky to have a +9 Superfeline kill even one Relic Doge. To make matters worse, even if you can get True Superfeline, it's still a rather situational unit for how much effort is needed to get it.

** The "Baron/Gauntlet" stages that pit you against the same set of enemies over and over at increasing strength levels, like Baron Seal and Le'Grim, aren't well-liked by the playerbase. In addition to being repetitive, the concept is seen as a dumbed-down Heavenly Tower -- and, unless you're [[BribingYourWayToVictory packing strong Ubers]] or willing to stack max-talent Cyberpunks for a long time, good luck beating the final stages due to the ridiculous stat inflation that'll be present on every single enemy. To make matters worse, there's a 30-minute cooldown after you win one of the stages, and before 10.7, the Baron boss maps needed you to do them ''60 times'' instead of the current 20.
