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 4.1.1 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 4.1.1 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 4.1.1 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 4.1.1 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 4.1.1 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 4.1.1 patch notes
