Thaddius

[Sword_of_Doom]

Negative Charge and Positive Charge are periodic effects that check every 5 seconds. Between those five-second intervals, they don't care where you are relative to one another. So run directly through Thaddius, in a straight line path to the other group. You'll run through oppositely charged people doing the same thing, but so long as you're on your correct sides before the debuff ticks 55 seconds, you'll be fine.
Well, there's two lag issues at play. The first one, which I experienced personally for a while, was that older hardware servers (hi Stormrage) simply couldn't handle the Negative and Positive Charges. Each of these effects checks every other player in its radius every 5 seconds to see if it blasts them or buffs them, which is 40 buffs checking 19 players each = effectively, 760 buff events needing to be processed every 5 seconds. The usual effect was massive ability lag, but the server wasn't above randomly disconnecting people (BZZZAPPP!).

That explanation really explains why some machines can't handle this encounter. Also, i can't imagine doing this event on Stormrage considering how difficult C'Thun was when i was on Stormrage. I am quite impressed that you guys do this event. On Cenarius i have zero server or client lag. Its remarkable the difference between Stormrage and Cenarius. New Hardware is the bomb and currently we have 6 guilds on the Alliance side that have 6 or more bosses down and 4 that have 8 or more (2 are currently working on the 4 Horsemen). Personally i think its largely because of the hardware.

Thanks for answering the questions, that helps a lot:) Our MT has 5/9 Dreadnought and is Prot Spec and our OT has 5/9 Dreadnought with Thunderfury and Prot Spec. We also have a Fury Warrior with Thunderfury. Not sure how much of a difference that makes on this fight. So tanking was not the problem even though when our MT went down it was game over fast.

Its too bad that this fight seems to be based off how good your computer is. Now i see why there was a lot of complaining in R&D.
