Personally its a "omg I have mana" compared to the old "omfg I need mana song but brd isn't my slave".

The only place that smn would be short on mana would be the raiding contents, so this change would only be considered a "buff" by people who raid as smn in FCoB. My group's been clearing T13 for a long time now, so my static is very geared, thus fights are lot shorter now. A very clear change would be before the adds phase in T13. I used to run under 500 mana back at the days, then before 2.51, I would be still over 1k. Now, after the mana changes, I would ruin2 spam about half of my old ruin casts, and I would still end up with almost 1k mp.

I haven't been playing serious mode smn in FCoB after 2.51 but I feel like with the mana change, if I continued my old ruin spam rotation, I would barely ran out of mana. That's just me. Can't take the game too seriously now with coil lock out removed and nothing new for 3 month.
