I like how people are for the system but still want the system to give more slots...
I'll try and play and see how the system turns out.
I for one admit I'm not please by it, again for this kind of reason :
If my skill slots are very precious, it's hard to imagine keeping a skill like "Rain" equipped in the mid to late game for those times when it's minor benefit becomes very strong, when it's competing with a "Winterblast" and "Fireball".
I really don't see how this system actually manages to nerf mages. It just casts out (no pun intended) minor spells from combat, which is kind of lame.
