I don´t think this one alone is best solution. You simply hide 170MP engineer behind VP for some time and you still have almost guaranteed wipe if he doesn´t came with sweepers.
Also you almost always leave commandos hidden near demo to kill any1 who survives explosion.
It may be intersting idea, but it will only make demos harder to use, it won´t solve problem. demos will still wipe lone squads
- It make you invest 90 muni + a squad, and if someone spot your Engineer, near a vp, they will be more vigilant.
- You will not play the "plant and forget until some squad decide to visit the one shot kiss" in multiple locations, or you will loose map presence
- S mines have a sign, and demo require an engineer at least at "a balanced number here" meter to be detonable, seems fair.
PS: my main factions is soviet in 2v2 random, and i am rank 49, so i am not really an anti soviet fanboy, i just want a better game for everyone
