Right. I've seen a ton of complaining about vengance/vigilance jugs/guardians in gen chat, about how over powered they are (despite significantly lower dps than mara's, snipers, commandos and smugglers.) I don't know if this is the general forums attitude or not, and I don't feel like checking 37000 topics to see, but for once vigilance is in a decent place and i want to see it stay there.
Guardians kill you, because you're dumb. Now, I can't blame you, i have/do make the same mistake. Attacking into sabre reflect is how you die. It reflects damage to the attacker. I don't actually know it's damage cap, but it's at least 4698 damage, as shown here http://www.torparse.com/l/668240 at 01:47:23.783
So, the smart guardian waits for the super powerful mulit hit attacks (cull, full auto, master strike,, series of shots, force lightning, chain lightning, disturbance, ect. i can go on) and starts sabre reflect and you don't notice. Now, because none of the individual hits deal a ton of damage alone, sabre reflect reflects the full damage of your ability at your face, and you've now gone through 5-15 k of your own health. Because you're an idiot.
Again, I can't blame you, i have missed it and killed myself too. It's easy to miss. It's your own damn fault.
The correct response when you see it (on guardains, they get a glowy electric aura) is to stun them, or pop defensive cooldowns, or run away. Even just canceling your move and standing there is better than attacking.
I'm hoping it's not a problem, but vigilance guardians seem to be fotm atm, which is usually followed by nerfs, and i don't want guardians falling back to useless like they did after the tank smash fiasco of like a year ago.. If you think they're op, they're not. They're decent, at best. You're being killed by idiocy.
