This has resulted in quite a few deaths, but the latest case really gets to me. The trans leading into the last area is a chokepoint. It's bad enough that you've got to trans through it one by one, but when you step through and scrags immediately charge you, it's just being murdered on a trans. It's hard to click, and when i went through earlier they just smacked my invisible mage immediately, causing him to auto attack. With the attacking motion in play, it was impossible to even use the trans then and he died immediately.
It really needs to be set up more fairly.
Edit: and he had gone in, of course, because someone else had died unable to get through, putting the body on the trans and creating the whole scenario of dying as soon as you port in. Which, of course, was followed by the third member of our party coming through and unable to manuever with giant scrag models and corpses, resulting in him dying as well.
