1. Channeled flame/frost/shock spells are awesome, yet lose usefullness and disable mana regen* (an additional issue)
2. Mana regen completely stops during casting, leading mages to spend portions of fight not casting and running around like a fool
3. The bolt spells at apprentice are basically the same at expert level, just a better mana per damage cost
4. Adept level spells are the best overall having an additional aoe added and negate the need for expert level spells
5. The wall of fire/frost/shock spells lack power and coolness factor, area of effect and size should be increased along with damage
6. The perk trees for magic seem rather unispired and lame (archery is one of the most interesting and exciting trees)
7. lack of usefull spells outside of destruction, aside from conjuration summons (but why let something else fight for you? =) )
So here is what I suggest:
1. mana regen unchanged by combot/casting
2. Channeled spell, burst spell, wall spell, bolt spell available at level 1, grow in power and mana as you level skill
3. Alteration telekinesis gain combat utility as a force push spell
4. Illusion spells lose level cap limits, have a chance to break on combat
5. More exciting perk trees
6. reduce effectiveness of -mana cost enchantment stacking, add reduce mana cost of all spells enchant (maybe erase all the others to begin with)
7. Constant effect oak/stone/etc. flesh spell, drain mana on hit instead
8. Ward spells negate physical damage rather than increase armor, as they do vs spells
9. Allow conjuration pet to recieve equipable gear at highest perk (for those that like this playstyle)
10. Add new and exciting spells!
Other ideas etc. appreciated!
