Ok, it's a bit silly that some people break the STF mechanics with dispersed tricobalt mines, but maybe the devs can find a way to make the cubes/gates/transformers fully invincible instead of applying a healing effect.
Apart from this matter a general nerf to tricobalt mines still seems unnecessary to me.
hehe.... Trics USED TO not work with mine skills. I see no reason to change it back. Why? Back then mines were irrelevent. Now they are a serious threat! BTW FaW can destroy mines.
the easy counter to mines is to avoid hitting them. mines are largely immobile after all.
