Today I thought about having toast for breakfast, but then I realized I had some milk and decided on corn flakes instead. Then I drove to work and sat at my desk for a few hours doing nothing. Then I went home.
WE DON'T CARE. If your "adventures" have no clear relevance then why are you wasting space with them?
We haven't tried Vezax hard on 25 yet, however we did kill him on 10 man yesterday (hard mode) was a lot easier then expected. I was specced FFB (normal spec with Imp. Blizzard for Molgeim) was thinking of going frost for it but decided to try FFB first; the kill wasn't fast at all somewhere around 7 minutes (somewhat crappy group composition) and I was able to plain spam FFB (ignoring LB and HS) during P1 and start with HS and LB when the add spawned, ended with around 2k mana which means I could be more aggressive in P1.
Not sure how this information translates to 25 man, but guessing I would say FFB can be sustained in 25 the downside is the lack of survivability Frost can bring.
