Gnomish engineering problem

Hello,

I am encountering an unusual issue with Onyxia server. I am a Gnomish engineer and I just made the net-o-matic projector and a Shrink Ray. My problem with these 2 items is that they backfire WAY too much compared to any other server I have played. In an absurd rate I would say.

The Net worked 2/11 times and the shrink ray - I just made it, tried it 6 times and in 6 times, they all backfired. All the others server I played - this never happened. Sure, it used to backfire once in a while, but not the point where I feel it's detrimental to my gameplay to actually use them.

Do you guys have the same experience with these kind of items ? Do you have the same experience as this server in the past on other servers?

Thanks
