Currently, mines in higher ranked battles play a completely different role than mines in lower ranked battles. Higher ranked players use them all the time, as flag defenses, to help finish off an approaching enemy, or even to damage a tank they've "jumped" on. There are even sometimes mammoths' whose job is to trigger all the mines they find. None of that ever happens in lower ranked battles. The reason for these differences is that the hulls get stronger but the mines don't. A mine can instantly kill any M0 hull, but may take multiple hits to destroy a M3 wasp. Also, as players rank up, they earn more crystals but the price of a mine doesn't go up with it. A single mine might be a lower ranked player's entire battle fund! A solution to this problem would be to add M1, M2, and M3 mines. The mines of a higher modification would do more damage than a mine of a lower modification, but also more expensive. Lower ranked players don't need all the damage that mines can do, and can save some money buying weaker mines. Similarly, higher ranked players need stronger mines, and can afford to buy the stronger ones. Also, unlike the hulls, turrets, and protection modules, players should be able to keep the mines of lower modification they've bought. They could possibly micro upgrade their mines, as well as maybe their other supplies...? Again, this is only a suggestion. The idea isn't perfect, of course. Does TO want mines to have a constant role? How would TO transition from the current mine to mines with modifications? Would there need to be a way to tell the different mines apart when they are planted? Should they have different cool downs?
