A couple of arkfall questions

I've seen a lot of people coming to Arkfall and parking their vehicle right next to "crystal". Now, are those players just newbies who don't know better, idiots who want to aggravate others just for fun, or is there some deep, tactical meaning to this?

Several bugs have areas on their bodies where damage appears to be higher. Mouth, ***, underbelly and so on. What is the difference between damage done to those areas and damage done to other parts of their body?
Is it more sensible to employ tactics and try to shoot mainly into those areas or is it better to just go berserk and shoot wherever it flies just so it hits them?

Damage done to areas that are light up usually means you can do triple the amount of damage compared to the normal parts of the body which might take you almost 10 minutes just to kill one if you dont hit any of the light areas. No reason to do Arkfalls though until they fix the loot issues thought to be honest.

Hitting weak spots does critical damage and the amount will depend on the critical multiplier of your weapon. Some only do like 1.5 times critical damage and others do 3, 3.5 and even 4.2 for the Wolfhound pistol I think.

If you go into the options on EGO wheel and turn on damage numbers you can see how much damage your shotsa do, personally I think it should be turned on by default
