Don't be a fool a Blade Dancer don't even have to enter a bubble,you can wave it and who's ever in there…job done.Strangley enough I've rarely ever seen that done even when i use to play with my defender. Also if i do enter the bubble for the most part i win the majority of encounters,a skilled blink user can charge at the bubble and the titan is by default gonna assume your coming in now and just once you get near it then just blink over it and most players won't have enough time to turn around unless they got their sensitivity really high.
