At the same price as Triple Darts, the Spike-O-Pult was simply a much less powerful upgrade than its opposite number. We’ve increased its pierce by over 100% which should bring the two third tiers more on par with each other. The slight reduction in price to Triple Darts will hopefully make the decision on which upgrade path to take that little bit tougher! — Update notes
The Apprentice’s Fireball upgrade is really useful in earlier rounds (especially if your opponent is piling on the pressure with tightly-grouped eco bloons) but it currently gets overwhelmed a little faster than we’d like it to. Buffing the explosion radius should help with that. — Update notes
Much like the Ace, the good old Buccaneer hasn’t seen any balance changes for quite some time and still has relatively low use-rates. We’ve slightly reduced its base cost and taken quite a chunk off the Destroyer upgrade which should make it more viable in the early to mid-game. — Update notes
The poor Monkey Ace has been neglected in recent updates and we don’t see it flying around the battlefield as often as we’d like. We’ve reduced the prices of two of it’s more popular upgrades as well as bumped up the damage dealt by its activated ability. This will hopefully make it more useful in the later rounds when MOAB health starts to scale! — Update notes
Placing and upgrading a Heli-Pilot[sic] to its third tier isn’t cheap, so we think it should be a little more reliable when it comes to stopping lead bloons. Increasing the attack speed of Razor Rotors should help it achieve that. — Update notes
The Tack Shooter’s second upgrade path is rarely seen in arenas, especially in Ceramic Crucible and above. We’ve reduced the prices of the first three upgrades on that side to help make the tower more worthy of that valuable space in your loadout. — Update notes
In the 4.1 update, we reduced the eco penalty all the way from -$1000 to -$600. It seems that this change was perhaps a little too drastic and we’ve noticed that bloon eco is currently outweighing Banana Farm strategies, especially when you consider that eco players have a 4th attacking tower. Increasing the eco penalty of fast cooldown ZOMGs should help make both strategies just as viable as each other. — Update notes

Version 4.3.1
Version 4.3.1 released on 30 May 2017.[2] It introduces even more balance changes and Tower Skins.
Other than to use the Blade Maelstrom ability, the Tack Shooter's second upgrade epath is rarely wandered down by Battles players. The feeling here is that the Tack Sprayer is, currently, more reliable than its opposite number, so we hope this increase in pierce will correct that and give players more of a choice when it comes to picking which path to take. — Update notes
Since the last round of balance changes, the Mortar has become much more popular recently and crept its way into the heart of the meta. Whilst we're currently quite happy with how it's balanced, the Big One upgrade is a little too powerful for the cost, so this increase will bring that more in line. — Update notes
The Monkey Village rarely gets an outing in the higher arenas and we tend to only see it in certain Club rulesets. We've lowered a whole bunch of prices across the board to make it a little less of a commitment for players to place and upgrade. As well as that, the MIB ability has been changed so that it no longer stacks. We found that it was easy to exploit and simply too powerful! — Update notes
We don't see the Dartling Gunner[sic] out on the battlefield as much as we'd like and this could be down to it's[sic] relatively expensive placement cost. We've lowered this slightly and increased the pierce of its Powerful Darts upgrade to hopefully make it a more worthwhile tower to include in your loadout. — Update notes
As it stands, the cooldown timer starts as soon as you tap the ability icon, meaning you're not required to wait the full period before using the ability again. This change corrects that and it now works as intended. — Update notes
The COBRA has always been a popular tower, but we've seen an increase in use-rates over the past few weeks, with its Bloon Adjustment upgrade being an extremely popular win condition. This price bump should make it a little more difficult for players to spam 2-0 COBRAs. We've also increased the cost of the Misdirection upgrade to make stacking the ability a little more difficult. — Update notes
