So wait...even though almost every other subclass has a super that makes you have varying degrees of unkillability...and at the same time kill things easily..having a defender Titan do the same would be bad? Don't forget the Titan shield also has 2 huge handicaps of "not moving" and "being easily destroyed"

Hunter does not get to become unkillable for either of his supers. And titan doesn't only effect him it's for his whole team! So yes it would be very unfair. Also your whole team gets buffs for being in the shield also.

The titan in the bubble shield is not invincible. The hunter bladedancing gets increased health/armor/whatever. Pretending like other supers don't also buff the defenses of other subclasses a large amount is just silly. The whole team gets it? Nove blast it and kill the shield and most people inside of it...or just..move. Since it is the only completely stationary super. A super that does not kill and can not move should have more benefits then "making you harder to kill, but you aren't killing anyone else either unless they are stupid and run inside it".

Also this would upset the balance of p.v.e. Where people would just have a lot of players using Titan and able to stand still while killing bosses hitting there critical spots and just constantly using bubble shield, for instance the raid where there could be 6 titans, I doubt they would ever all be out of shield if they took turns( generates 2 orbs of light so they would get 10 orbs of light before it was there turn to use there shield)

It is impenetrable meaning that there is literally no way to fire back or retaliate against (before destroying it). Also other supers get shield which the bubble shield also can give to your team as well. Jus think about this for a secound. Does having a 3v3 where you are playing against 3 titans all using this bubble shield taking turns using it so there is very little time when they need it and don't have it and every time you engage them they put up a stupid bubble of death and all gained extra shields (like other supers give) and you couldnt shoot back because the bubble. There would be no way to stop this. Other then maybe a invisible blade dancer, but then again the extra shield buff would make it take a couple hits to get a kill, or using a nova bomb on it which they would def see coming and either move or kill you before it goes off. So the only way to stop it is a lucky kill using your super or running away until it goes away

The Titan gets the same degree of "unkillability" also. When using that shield Titans with the Blessing of Light get the same shield that the other classes get. Plus that bubble shield is just too good in control when capping or defending points.

Other classes which get a shield or whatnot with their supers also get abilities to give them a huge offensive advantage. The defender titan does not. It is only a defensive advantage if the people you are against do not have their supers available to destroy the shield.
