While Boomerang excels as an early game tower and so we are conscious to not make its later tiers overly strong, we still want all upgrades to have some viability. Perma Charge is probably the weakest of Boomerang’s tier 5s and the other two aren’t particularly powerful either, so we think it’s well deserving of a buff. — Version 4.1 patch notes
Ice Monkey is useful for early game defense and late game support with stalling and debuffing, but provides pretty much no MOAB class damage with any of its upgrades. We would like to give it a bit more to offer by allowing Icicles to attack and damage MOAB class bloons. It won’t deal massive damage to them but it can be greatly buffed by Fusty the Snowman, so we will be curious to see what impact this change has. — Version 4.1 patch notes
Since it’s hard to get much use out of Sniper in the early game, we’re giving it some simple early game buffs and improvements to crosspathing. — Version 4.1 patch notes
We would like Aircraft Carrier and Carrier Flagship to be more effective in bloon cleanup, which we have done by increasing the pierce that the darts have against regular bloons but not against MOAB class bloons. For example, Carrier Flagship’s darts remain unchanged when hitting all MOAB class bloons, but they have the potential to hit 4x as many regular bloons now. — Version 4.1 patch notes
Ace Monkey has a pretty easy time getting through all stages of the game, with the potential to be extremely efficient in the early/mid game when targeted optimally. We have slightly nerfed Bomber Ace so that its bloon cleanup isn’t quite so solid. — Version 4.1 patch notes
Mortar Monkey still excels in the current meta. We have reduced its blast radius, but increased (and fixed) the buff that Jones and Bones give it so that it remains similarly effective when paired with either of these heroes. — Version 4.1 patch notes
We noticed that Ray of Doom’s pierce was remaining at 40 (the pierce that 4xx has), however this was never intended. We have brought its pierce up to its intended value and given it another small damage buff on top. — Version 4.1 patch notes
We still feel that Wizard Monkey could do with some minor improvements, with a slightly cheaper decamo and some added crosspathing changes that make sense. Prince of Darkness’ buff now applies to itself, as it was never intended for this not to be the case. — Version 4.1 patch notes
Ever since Ninja’s major nerfs a few updates ago, it has not been at the level that we would like. We are very conscious to not repeat past mistakes and over-buff it’s early game, so we’re just making very small changes for now. Bloon Sabotage has also been changed so that it can be used more reliably and easily when defending ZOMGs and BFBs. — Version 4.1 patch notes
Druid of the Jungle very recently received a big nerf and while it certainly still is strong, we’re not yet convinced that it needs any more significant changes. For now we’ve decided to just make some small price adjustments. With these changes, it’ll now be slightly more expensive to quickly and easily buy 1xx on your 030 Druids as a very cheap option to strengthen your defense. — Version 4.1 patch notes
Recently, we altered Overclock so that buffing a parent tower will also buff all of its child towers (eg sentries). Additionally, in this update we’re fixing a bug with this, meaning that newly spawned child towers will now correctly inherit the buff. With these changes, it makes Sentry Champion incredibly strong but only when buffed up a lot by the likes of Homeland Defense and Overclock. We have decided to change Engineer so that the spawn rate of its sentries can no longer be affected by attack rate buffs, but we have also greatly increased Sentry Champion’s regular damage so that it’s much stronger on its own now. — Version 4.1 patch notes
