Version 44.1

•  If the player has more than five Mermonkeys with Echosense Network, selling any of the first five Mermonkeys that received the upgrade no longer removes an Echosense Network buff stack from all affected Mermonkeys regardless of the number of Mermonkeys with the upgrade remaining (bug fix)
  • Note: This bug would cause the number of stacks to be lower than the number of Mermonkeys with Echosense Network

Version 45.0

“

Echosense Network hasn’t felt like it is doing all that it could, so we have increased the maximum number of stacks to raise the ceiling of use here as it is meant to be slow ramping with a high space & cost investment to build heavily into.

Version 51.0

“

Mermonkey weren’t^[sic] feeling they favoured their natural habitat enough, so their Water Placement bonus is getting a boost.

Version 52.0

Last update many players felt blindsided when Brickell stopped applying her buff to Mermonkeys since there was no mention in the balance changes section. We would like to apologize for that - it was tasked internally as a bug as it was indeed unintended to work that way. We then left the issue alone for a long time, mostly due to other more pressing matters, and this issue fell through the cracks. In retrospect, it would have been better to treat this as balance rather than a simple bug fix due to how much time had passed. Reading through your feedback, we did consider just reverting the change, however the bigger issue that the feedback reinforced to us was that players considered Mermonkey to be so bad that it was only a "good" tower when used in combination with a single, water-only hero. This sort of forced synergy goes against our design intentions - namely that Mermonkey being our signature amphibious tower should be able to stand on its own without being balance-locked to an interaction with a single hero. With all that in mind, we feel Mermonkey's highest priority right now is large sweeping buffs to each of the paths, so most of the following changes are our first step towards this starting from the low tier crosspaths.

Echosense's previous change was quite an overbuff and many players felt this invalidated the water placement bonuses so we are lowering this again but not all the way back.

Mermonkey ended up somewhat underrated and overbuffed, mid tiers for top and middle paths have really stood out here lately and need to be reigned back in line.
