Ok cheetah needed the buff but the mines , in my opinion need to be dropped and not thrown. If you make the damage 20 - 30 % less it wouldn't be so bad . Plus only 3 mechs can do something about these mines ( Guardian, kill shot and juggernaut ) killshot can dash past ,guardian can just say bye bye to everything it's ability touches,  and juggy has his perfect (well once perfect) shield. But the distance it can throw + the damage + and blast radius makes it fell more like a grenade than a mine. On top of that the mines in my opinion need to leave the field no later than 5 seconds after death. In other words you buffed the mech but you buffed is damage and that was it. Agian in my opinion you probity shuld have only given its ability a 40 - 50 % buff and the health a 20 - 35 % buff. And maybe make areis shield a lil bit more robust , make it touch the ground so it can block the mines. The only reason I bring areis shield up is that I saw that one of the moderators stated that areis shield could take the damage from the mines(can't recall which post it was stated in) . Im not exactly sure how low the hit box is for the mines but it's low enough to get past areis shield .
