User blog comment:PlantShielder/The Epic Leaking of the Bloons/@comment-10863056-20141023203514/@comment-24170389-20141023212448

First - I CAN'T make things that has MORE than 30 HP, or else, it will only heal when the bloon/blimp has less than 30.

Second - An ability that costs HP just will make it lame - specially if the ability is overrused.

Fourth - I can't make skills which have cooldown. Also, Solidify skill would be too OP, even with recharge - it could be used infinitely, if the person avoids the attacks and times correctly, just like how Regen Bloon's regenerating passive skill is OP...except, well, Regen Bloon's regenerating skill delays A LOT to you BE SURE that you healed a lot. Also, for 7 HP, a Regen Bloon would delay 35 seconds, while Solidify skill delays 20 seconds - 15 seconds less.

So, yeah, these ideas were damn rejected.
