For me, problems with C4 are:
- Too cheap (at least currently)
- Too powerful when multiple C4 stacked
- Min. detection range
- Almost impossible to disarm even with high traps
Solution:
- Price for detonator will be increased probably to 2500, HQ materials will be a bit harder to get after wipe,
- Explosion of C4 will remove other explosives in nearby area (equal to splash), including containers/bodies to prevent stacking fast powerful damage,
- Min. detection range will be changed to 3, if it doesn't help much, then to 4 (but 3 should be enough),
- Disarming formula reworked.
There will be also 1-2 new types of explosives, details not specified yet.
Btw: stop spreading misinformation about private mines being removed from the game. They will not be removed and I never said that they will be removed.
