Version 4.3.1 is a minor update to Bloons TD Battles 2 version 4.2. It introduced Over the Air updates, made tweaks to Leagues and fixed some bugs. It was the first update to receive Over the Air updates, one for fixing a visual bug and another for additional balance changes.
We were a little too successful in trying to increase the popularity of the Sniper Monkey as it is now the single most used tower in the game, surpassing even the Banana Farm. Sniper's popularity is due to it's versatility as an income source that also excels with both group popping through its shrapnel shot and at single targets with its high damage. We believe the primary culprit for Sniper's dominance is the x3x Bouncing Bullet's ability to create multiple bursts of high damage shrapnel so we have capped it to 1 burst per shot and also moved the 1xx shrapnel damage upgrade to 3xx so that only dedicated top path snipers can benefit from it. We've also increased the cooldown of the Supply Drop ability and added ability cooldown reductions to the bottom path to create a choice between the more offensive 240 Sniper farm or the more efficient 042. — Update notes
Super Monkey is proving to be a bit too good as an early game defender which isn't in keeping with its intended use as a late game powerhouse. We're increasing its base cost so that it's harder to get out early without impacting its late game usage too much. — Update notes
As we describe in Bonnie's balance changes, the BEAST is proving to be much easier to pop than we anticipated. The Spike Factory is the worst offender for this and the Spike Storm Ability is guaranteed to instantly vaporise[sic] the BEAST. We prefer not to add special exceptions to the rules but in this case we feel it's warranted as trying to nerf the Spike Factory so that it does a fair amount of damage to the BEAST would make it unfairly weaker against everything else. — Update notes
Bonnie is extremely popular and appears in a significant portion of matchups across all arenas. This isn't a concern for us because, like Etienne, she enables a variety of strategies rather than just one or two so her popularity shouldn't make things stale. Despite her popularity, her win rate is well below average in the Hall of Masters so we don't believe she needs much in the way of nerfs. That said, one common complaint is that Bonnie gives too much early game income for too little investment so we are reducing the value of her base Minecarts and moving that value into the upgrades, making her less efficient right out of the gate but keeping her the same strength once she's a few upgrades in. We have also seen that it's much easier to get full value out of the BEAST than we anticipated, essentially turning her ability into a "free money button" at higher levels. We've kept the amount of cash contained in the BEAST the same but increased the amount of damage required to extract it all. — Update notes
