With the drastic reduction in sp costs for many of the staple damage spells I am considering not using metamagics except for boss fights when dps trumps conservation.
In the past, maximize made sp sense for any lv. 4 nuke or higher, as 2x damage only cost the sp to cast a lv. 4 spell. Now, you can case 3 fireballs for the price of 1 maximized fireball. Or 5 scorching rays for the price of 1 max. Or to get really silly, 7 niac's for the price of 1 max. Particularly with sorc. who can really spam spells, this seems the way to go.
One problem I see is that one of the great benefits of SLA's is the free use of metamagics. However, if I end up wasting tons of sp in inefficient castings between SLA cool downs (which are only getting longer), or have to waste time clicking my metamagics on and off, the benefit of the SLA seems muted. (In the context of Archmage evocation and the new elemental PREs, free heighten for other ARchmage SLAs still seems good).
So what is the communities thoughts on metamagics going forward?
Edit: Forgot to add: in the context of low level play. At cap when you are using higher level spells, and have significantly larger sp pools, it makes sense to keep your metamagics running most, if not all, of the time.
