So it isn't harder for melee of any level to avoid these mechanics you are saying? When some can literally spawn on top of you? What part of that are you being purposely ignorant about? Am I also the only one that has pointed that out either? No, but yet here you are still trying to argue this point when even you said you die to these mechanics. So why are you still arguing against this?
Finally as these invasions go on less and less max level toons will be doing them as the shards get people next to nothing. So what will happen? You will have more leveling toons doing it and them tagging and running causing these final stage fights to go on for long periods of time. Has it happens a lot yet? No, but I have already been in a few where that has happened.
But , keep arguing against everyone you seem to be right.
