[b][u]Bungie Confirmed[/u][/b] Each infection creates a disruption/corruption in your guardian's light which weakens your link to your ghost. The infections' effects are cumulative. There are buffs to XP and reputation gains by being infected, but there are also significant negative consequences that will kick in once RoI drops and SIVA is released into the game world. When an infected guardian is first exposed to SIVA, the SIVA mutates the existing infection(s) and the following negative effects are applied, in order, based upon how many first-instance infections were contracted: 1. Diminished shield strength 2. Diminished shield recharge 3. Increased susceptibility to all elemental damage 4. Diminished weapon damage 5. Diminished super, grenade, and ability recharge rate These are very similar to strike and nightfall modifiers, such as trickle, elemental burns, etc., and will remain in effect until the community is able to solve the mystery of the origins and delivery of the first-instance infections thus allowing a 'cure' to be formulated and distributed. It is very likely that Bungie is doing this to ensure that the new content, in particular the new raid, is not completed in a day or two as has happened every time in the past. They can't make more or harder content so instead they weaken our guardians through an in-game mechanism that we, the players, actually embrace and propogate. Clever, clever creatures. Anyway, below is the source if you want even more details. [spoiler]DeeJ sends me spoilers through the electrical wiring. You can get the updates too, but you'll need a good foil hat to block the government's mind buffer protocols. Use Heavy duty foil, not that cheap thin crap, and make sure it fits tight. What? Yes. Yeeeees! I told them about the hats. Of course I told them to use heavy duty, I'm not stu . . . Oh, shut up! I'm not getting into that with you again! If you wanted the last sandwich you should have said something. Really, just stop. I'm tired. Don't make me take off my hat, ya bastard . . . [/spoiler]
