It seems pretty much everyone and their mom is forgetting something here. Something huge. Like, exploding blackholes on Mars level of "wait a second, I should pay attention to that..."
They've switched nearly all spells in the game to no longer have a base damage (or simply "1" as a stand-in) and spells are far, far more reliant on your Attack/Spell power. Alongside that, they're lowered weapon damage and upped how Attack Power effects its formula in order to help fix the "if you're melee you need a better weapon, if you're a caster any int increase will do" problem.
If you take that alongside most CC being within, I think, three categories and silences being niche and not present all over the classes anymore, low lvl PVP should be far less insane than it currently is.
Unless you're in a low enough bracket for enchanted heirlooms to proc stupidly high percentages but that's not really a problem after 30.
