i was complaining about sustain for like the longest time but i was shut down by negative reps : (

[Lammy]

I'm all for nerfing sustain, all because when it is too much it is boring, horrible, tragic, outrageous, stupid.

[Chance]

maybe i just don't pay much attention to people sparring or something but i haven't really seen any powerful sustains... other than asta i guess?

[Laemor]

There's a lot of them.

From my own experience, Asta is the only sustain that I can't beat so far (Though, this isn't just crystal/nature teraphim in her case).

Looking at it more broadly? Over the changes in TS, there were many alterions to spells that made their overall damage lower. Either through decreasing damage, or by increasing their CD.
When it comes to battling sustain builds, its either you have better sustain, or you have enough burst to take it down. Lower the burst potential for spells, and/or how often you can use your burst, and sustain gets an indirect buff by others having their own bursts be weakened.

The whole mana cap dr + sustained damage + sustain

The issue with these builds alone is the fact that they're done with racials that synergize hella well with what they do.

Like dr builds where you can go drakanite to get static dr on an aura, then have scales that give more dr, and then you have mana cap that also gives static dr teehee

and teraphim, where they can go sustain, buy racials that also adds on more sustain, and then another racial that does good damage that's relatively cheap.
