Mines should not be roadblocks designed to blockoff a route, they should be used to slow down the enemy. They should not be drop and forget because there's no way for them to get by, they should require to be watched over because someone could disarm them.
On Endor, there are only 3 routes to the flag, its hard enough already with a decent defence from the imps to cap it, but for a support to be able to constantly blockade the bridge by himself, having an unlimited supply of prox mines, it becomes almost impossible to cap. The rebels are left with either a ladder which they are defenceless against, where their back is also facing the enemy, or the spiral stairs.
This is not about nerfing them. I'm not saying make the explosion smaller, make the range smaller etc. I'm asking for a balance because right now they are imbalanced.
Let me guess, your one of the one that thought BFV was balanced with the Noobtube launcher and the rambo kit?
