Compulse penting on a sorc:
Grab 3 from a higher area means you go there slowly, takes time, then grab 3 decent ones, bring them back, keep them alive.
I have seen them die often enough when I didn't support them with c2. So running around and grabbing pents only lasts a short time.
Then you also have to keep track of time for spells and time for transfer.
Do this on a gpot, then you probably use the gpot to get the high ones. By the time you can transfer them, you already need to use your 2nd gpot. And not THAT much exp to show for it. Then waste more time grabbing new ones.
And when the 3 compulses get surrounded, and you run away to grab some more pents, then you will be fighting solo anyways. So you can't raise compulse and not focus on solo fighting. With some bad luck, someone solves right at that point, you need to kill lots of gargs to get back to your compulses, to see only 1 is left, at 10%.
So...sure, some people make it work. And it can be fun.
In the right spot, with quick solving pents, it can speed up things very well.
About Drinks post:
For mere mortals this won't work

A new player, no alts, will not be able to do that for a very long time.
No full gear, no dragon gear, no ss-ed gear. That comes much later, quite often.
The mana issues that Drink mentions. I suggest making concentrate cheap, instead of the current expensive version. Since you need to raise a lot of spells to make them work, you have to keep making choices. That's for a sorc around col to noble very true.
Getting a break on mana issues would help, and would fit a sorc.
Drink suggests no fightback on a sorc. With low AV, low sword skill, this means you need a high curse to keep landing. Again, mana issues. Works for RB2 sorc with full gear (and a bit sooner), but not for a new sorc.
Dispel and immunity:
No immunity and low AV means you are a very easy victim for gettings cursed, stunned and then blasted to bits.
Dispel would make them like a hara, too much of a copy, I would say.
But a little immunity could go a long way.
Perhaps have sorcs get a sorc shield (like necro sword) that grants them some immunity? Maybe add concentrate (see mana issues before) and 60 str, agi requirements.
A new spell that works like harden, but from mana, that gives immunity for some time, would be nice too.
But...sorcs have a lot of things to raise as it is.
