I noticed alot of players were haveing a hard time with spellcasting even more so than last time.
How about the game uses a combo of Very simple Runes with voice commands.
Example: draw a simple Rune that means Bolt and say "Fire"
thus getting a “FireBolt” spell.
anotherExsample: Draw a Rune that means Ray and saying "Arcane"
thus casting “arcane Ray”.
This will allow the game to have easier runes to draw without oversimplifying the class and add more Spells without making entirely new runs for every single Spell. this way if you need a Bolt spell for light or ice just draw the rune for it and say the element you want to use for it
Ofcourse this is just anidea nothing more. please feel free to consider some variation of it.
