None of those attempts on me were from anyone looking for a
challenge. I was fighting NPC's each time. Looking at their
gear, both of them were much more experienced than I. And
their RP reasons were either non-existent or lame at best.
Yet, they didn't hesitate to spend the coin to mask their
approach and get the easy kill.

So if you say this is a low level 'phenomenon' then tell me,
seriously, do experienced players really need the benefit of
invis potions (and holy ####, fly potions too?), correction,
EASY TO GET invis potions, to gank noobs? Isn't their gear and
other prep knowledge enough of an advantage?  And I say noobs
because I know for a fact I wasn't the only one that warrior
or the shaman used that technique on.

CF has always been brutal for noobs. I expect that. I dunno if
it was just my bad luck this time or what, but experienced AND
invis non-melee players was over the top for me.
