...as long as the mechanics are done.
I'm in a Heroic only guild, however another guild our GM knows asked for a DPS to fill in a 20th spot they were short on for the night so I got volunteered. They had finally cleared Cenerius and this was their first time going after Xavius.
Needless to say I was expecting a train wreck.
Long story short I was a bit of a nervous mess listening to them going over it. I didn't want to be the nublet who screwed everything up as the guest in their raid.
After two quick wipes where designated people missed dreams, on the third time we basically bulldozed through and I even managed to live till the end. While I did spike to the top of the meters for the first 85% or so @ 980k'ish (that is what Ret Paladins do lmao) I slowly dropped to the lower end of the pack at around 400k sustained. I guess its not all bad consider the caliber of sustained damage going out. I was basically a minor league player getting thrown in with the big league boys and girls.
So how hard are the rest of the bosses in M-EN? I don't suspect our guild will ever go that path (we don't field a roster big enough nor want to) but it does perk my curiosity.
