Gotta agree.. There's only so many times one could pass on advise and suggestions, with them being completely ignored before one just gives up..
Examples..
1.Have a bulk buy option for walls
2.Dual leaders
3.Reintroduce bonus units from the past at the same difficulty that they once where for new accounts (deadly bridge jumper)
4.Add a guarantee per level in a crate event that you will get the desired prize (eg.. After 20 opens on box 10 you will defo get the prize) .. This reduces unfair gambling
5... And so on
The community have done their part in the past, but Gree need to listen
