why not classic resists?

[Faerie Blossom]

Maybe it's just because I play casters and the non-classic resist system benefits me, but I don't understand why this is such a big deal for everyone. A week ago in Guk I chain casted snares and roots on a blue con FoH cleric I think (Soda), and after 10+ casts all being resisted she was able to make it to zone and get out safe and sound. And once in OoT, I chased a Nihilum wizard around my level out, and he came back to nuke me down with ease after resisting 2 of my nukes. All I could land on him was Winged Death. After the fight we chatted for a bit, and he said he had put on his banked resist gear before coming back, which was why he resisted my nukes.

It seems pretty balanced for me: wizard lands stuff on druid without much resist gear, druid can't land stuff on resist geared wizard. I assume Soda had on some pretty big mr gear, and had resist buffs up.
