This game would of been lot better turn based. Enemy wins initiative casts dispel there goes all the prebuffing or if the developers were smart and took a page from baldurs gate 2 book. Use some homebrew DnD rules giving enemy casters a speed bonus so they cast spells 1.5 times faster then player and attack more
Some have at first for wits, then poets pass'd,
Turn'd critics next, and prov'd plain fools at last;
Some neither can for wits nor critics pass,
As heavy mules are neither horse nor ass.
Those half-learn'd witlings, num'rous in our isle
As half-form'd insects on the banks of Nile;
Unfinish'd things, one knows not what to call,
Their generation's so equivocal:
To tell 'em, would a hundred tongues require,
Or one vain wit's, that might a hundred tire.
But you who seek to give and merit fame,
And justly bear a critic's noble name,
Be sure your self and your own reach to know,
How far your genius, taste, and learning go;
Launch not beyond your depth, but be discreet,
And mark that point where sense and dulness meet.
Turn-based has nothing to do with it. If you lose initiative to a pack of Dweomercats they'll pounce your ass with a flurry of Dispelling Strikes before you get to act on RTwP too. Unavoidable in the Varnhold DLC. Twisted Sisters have a Dispelling Wail as well. The big challenging fights have their share of quickened spells if you're not getting in there and disrupting them, which is easier said than done. As it is, Dispelling is a difficult task for both mob and toon, which is maybe an overcorrection from BGII but a needed one.
And if you're an Amish Luddite Stick-in-the-Mud TBtard who needs his mommy to fly in on her helicopter to cast Time Stop before every battle then there's also a perfectly functional mod she can install for you too.
