Use Helm of Saint 14 when you're dealing with suspected new pvpers (Low Levels) or for the first match you play. This minimizes the possibility that people are prepared for the Helm's Special Ability. There are times in a crucible match that I can't recognize the armor on a titan while he/she is chilling in a bubble, therefore the chance of me rushing into the bubble for a shotgun/FOH are reduced. Once I see some defender grenades being thrown around, I'm usually on my guard and are being wary of bubbles. Think about the camera from Bioshock 2 or telling a joke over and over the exact same way. This is the same philosophy as with the Defender Saints. Once an enemy has run into a blinding bubble, the jig is up and you (as the Saint Defender) have played your ace. The enemy team if observant/intelligent/ or communication focused, is now fully aware of the glorious sunlight of your bubbles. This means that they will often refrain from charging into your bubble, and if they are charging you need to consider two possible factors. These two factors are: The enemy is careless/stupid/overconfident. This opponent can be your delicious prey, falling repeatedly into your trap and placing themselves entirely at your mercy. Be wary that they might melee you until you die, since melee is auto-tracking, or get lucky with a grenade stick or shotgun blast. Lady Luck is a fickle mistress in this situation. The other factor is: The enemy is charging balls for you and they're super charged. If its a titan, back the f**k out and try to build the gap between you and the titan. (Often blinded titans will FOH when they enter the bubble, panicking and hoping for a multi-kill. ). Voidwalker Warlocks operate in much the same manner, they'll usually freak and Panic Bomb the shit out of your bubble. Hunters are a mixed bag, if you see a blade dancer coming bail son bail! Arc Blade auto-targets and will kill you even if they're blinded. Gunslingers are a huge coin flip. If you don't move when they enter the bubble they'll just blind fire and kill you, if you're flying around your shelter they might blind fire and miss. But you run the risk of them getting lucky and hitting you, and if they miss they'll probably take out your bubble with the GG.
