History YMMV / BloonsTowerDefense

** When it comes to Boss Bloons, the Tack Zone and MAD are very commonly used by players for both Bloonarius and Lych. The Tack Zone has great damage for its price and can handle the first few rounds with some support for Bloonarius's ceramics, and the maps where bosses appear usually play to its strengths. Meanwhile, the MAD has excellent MOAB damage and doesn't rely on buffs, making it useful against Lych, while still being able to benefit from buffs greatly when fighting Bloonarius.

* FridgeBrilliance: The fact that MOAB-class Bloons look like bombs, since they [[OneHitKill essentially act as a nuke if they bypass your defenses]].

** Similarly, once Quincy got buffed to become a relevant hero, the fandom shifted to making fun of Obyn. [[HowTheMightyHaveFallen Once considered the best hero in the game]], Obyn was done in by a combination of nerfs and PowerCreep -- in addition to his increased cost making him unable to be placed as a starting tower, his buffs applying to fewer tower types, and the slowing ability of his totems getting weaker, other support options were added or buffed to make them far more powerful, even with the bottom-path Druids he works best with. Gwendolin, Pat, and Geraldo are all much better options for buffing magic towers, and regular support towers like Alchemists will support the Avatar of Wrath fine without taking up your hero slot. As a result, Obyn is a SkillGateCharacter who's easy to use, but hopeless for beating CHIMPS on the hardest maps. Tellingly, the tier lists for CHIMPS place Obyn in the D-tier -- just barely above towers which are completely useless in CHIMPS, like bottom-path Buccaneers, and below Ben, whose money-generating abilities not only don't work in CHIMPS, but also lose the player money.

** The 38.3 update made the Total Transformation bugged by allowing you to link some transformable towers to whatever you want. If you link something to a dart monkey they become compatible with both Fan Club abilities, which allows you to greatly enhance the attack speed of the tower (Plasma Monkey Fan Club gives most projectiles the texture of the plasma balls, but this is only visual). You can also link almost anything to a bugged Wizard lord Phoenix and have the tower use its ability indefinitely, even if it is an income-based ability where they cut money-generating abilities after 3 minutes from the start of the round. In addition to that [[https://www.reddit.com/r/btd6/comments/164ll20/selling_bosses_with_the_new_bug/ this link on reddit]] shows that you can link the monkey to the boss bloon and then sell the tower to instantly defeat the boss. Finally, the bug also has an effect where linking a True Sun God to a tower and then upgrading that tower enhances the sacrifice power of the True Sun God, potentially allowing it access to damage levels that make the Paragons look like base towers. This bug would be fixed in the 39.0 update.

** Striker Jones in ''[=BTD6=]'' was originally this, at one point being much weaker than the other heroes. Before buffs, he was the only hero who couldn't pop a bloon that was immune to his attacks, whereas Quincy gets explosive arrows to deal with Leads, Gwendolin becomes able to pop Purples at level 17, Obyn's Brambles can pop Purple bloons, and Churchill's Armor Piercing Shells can pop black and zebra bloons. Striker Jones had nothing that could pop blacks or zebras. Even beyond that, he couldn't do anything against MOAB bloons, due to his slow fire rate and low damage. He was only really usable with lots of Bomb Shooters to support. After being the butt of jokes in the community for a while, he received heavy buffs to pull him out of this status.

*** Striker Jones was one in the early months of ''[=BTD6=]'' due to being the weakest HeroUnit and a generally outclassed tower. He's since been pulled out of this thanks to being buffed into usefulness and getting a well-liked alternate skin.

* HypeBacklash: Despite months of excitement for the Engineer's Paragon in the buildup to its release in 32.0, the Master Builder was panned once it finally arrived. It overspecializes in the first path's sentry-based mechanics at the cost of abandoning nearly ''every'' other aspect of the second and third paths apart from buffing itself a la Overclock at the start of every round and being able to pin MOAB-class bloons in place, essentially making it a Paragon-level Sentry Champion. In conjunction with how versatile (and expensive) Ultraboost and XXXL Trap are, it is generally seen as far from a worthwhile upgrade, and players were already clamoring for Ninja Kiwi to rework it mere days after its release, particularly citing how the first Support-category Paragon has ''zero'' support abilities, with even other explicitly offense-oriented Paragons often having some degree of team support.[[labelnote:Examples]]Glaive Dominus buffs other Primary towers' attack speed, Navarch can produce money while buffing water towers and Aces, Ascended Shadow grants global Camo detection, Nautic Siege Core buffs Heroes/Subs and can reduce cooldowns with Energizer, etc.[[/labelnote]] Ninja Kiwi addressed this by saying Paragons aren't meant to be just 5/5/5+ towers and don't need to equally feature aspects from all three paths, but the generally uncreative result of the final product, with people saying it's more of a Dartling Gunner Paragon, led to them stating that they are considering adjustments or even a full rework of the Paragon.
