The site has two rocks quite far away from each other if I remember correctly, but you’ll be far away enough from them so they won’t be an issue. And yes, the frigs pointing you will be your only concern since as soon as an enemy enters the system you warp off. Now reaction time + align time should give you about 10 seconds untill you´re in warp. So unless the enemy goes straight to your site immedietly upon entering the system and is ridiculously fast you should be just fine.
However. IF you have a really bad day and someone enters the system just as you start a new frigate wave (wave 4 or 6) and IF one of them points you, you’ll get a nice dose of adrenaline running through your body. The Wasp II’s, together with the omni links, will quickly dispatch of the frigs. You just have to hope they auto-targeted the right frig. In any case you should have started aligning, so as soon as you lock the frigs you blap them with your drones in a few seconds. Then ditch the drones and warp.
But that’s a fairly rare case. Most of the time you just warp off.
I have used webs before, both a single one, and two of them. But I reckon they´re unnecessary since your drones will handle frigs and BC’s very well, and on the cruiser waves you two-shot them with the guns anyway. So I just have 1 button (F1) for BS’s and cruisers and keybind one mouse-button for drones for frigs and BC’s.
MJD just seems like a wasted slot that would only be used very rarely, if at all. I’ve been ratting like this for a long time, never had a close encounter, I can count on one hand the number of times I’ve had a neut enter and I was in the middle of killing a frig with point.
