Soulstone Plains Bug/Glitch

[InstantDeath]

Hello,
In soulstone Plains arena, during the mining, players from the opposite faction can lure the engineers & drills near their Commander Elite ( the boss that looks like Terrors in Misty Woods ) and kill them there. There's no way to reach them, if you get too close, Commander Elite kills you in 3-4 seconds. Could you please decrease the range of engineers/mining drills so that players wont abuse it.
