Getting back different tier spells?

[Shougun]

I don't think we need actual spell tiers, but if the same spell simply looks more impressive every 15-20 levels or so (as in, it's the same spell down the line, but as the OP illustrated, the Fire spell's visual effects at level 1 vs level 20 would be drastically different), I'm all for that. No having to re-balance diddly squat, no superfluous extra spells, but gives more of a visual reason as to why the exact same spell is doing more damage down the line.

Edit: Seig edited his post so this makes less sense

Tiers are not superfluous. Though they do take up room lol.

Being able to cast a faster spell, or a cheaper spell on demand was useful tactically.
