The only solution for this is making some lower level spells easier to cast. Now fireball 2 is a no brainer thanks to its difficulty against fireball 1 and same goes with frostbolts.
Let lower skilled playes be able to cast level 1 spells more easier (maybe changing level 1 frost and fire spells) so they end up with better dps then trying to go for the level 2/3 spam with “misspelling”…
Hard working players will be rewarded with better dps as it is with other classes like if your trying to be an ok scoundrel or a pro scoundrel or ranger, etc…
I think we have to think smart and be able to figure out a way to “fix” this issue with the lowest amounth of work possible and this idea is not that bad and maybe just few spells will get affected…
Also an insight runemage explenation and tips video from developers would be able to impress some newcommers
