My biggest issue is that abilities that are supposed to PREVENT cloaking, such as tractor beam don't work at all to stop Donatra from cloaking in the first place.

I thought it was ridiculous the first time I saw it, she cloaked whiled being held in a tractor beam, and then just flew away. I don't care how good your cloak is, you still shouldn't be able to engage it while you are pinned down in a TB.
