Heavy attack builds are already weak. My Oakensoull build has near 90k dps and Rakkhat one has 120k, but it has much more difficult rotation than a beam build with the same DPS range.
So, standart requirement for vet trials is 90k dps. And with the next patch simple Oakensoul version of my heavy attack buiild will be below the treshhold. The Rackhat build probably not, but it is already not worth to use.
I tested only Oakensoul version:
Race: Dunmer
All points to magic
Mundus: Thief
Food: Witchmother's Potent Brew
Class: Warden, only use Animal Companions skilline
Subclassing skilllines: Asassination and Aediric Spear (for passives)
Active skills:
Screaming Cliff Racer, Deep Fissure, Wild Guardian form Animal Companions
Concealed Weapon (for speed boost) and Merciless Resolve from Assassination
Banner from scribing (Magic damage + Cavalier's charge + Heroism)
Blue CP:
Weapons expert (of course), Exploiter (cliffracer sets targets of ballance), Master-at-Arms (direct damage), Fighting Finess (more crit damage)
Red CP:
Boundless Vitality, Fortified, Slippery, Celerity
Sets:
Oakensoul Ring (weapon damage enchantment)
Slimecraw Epaulets (divine, magic enchantment)
Sergeant's Mail: body (divine, magic enchantment), lightning staff (precise, weapon damage enchantment), necklace (infused, weapon damage enchantment), ring (bloodthirsty, weapon damage enchantment)
Highland Sentinel (crafted set, all divine with magic enchantment): medium legs, light head, hands, sash, feets
Live server 91k dps:

PTS: 84k dps:

So, this type of builds already has low damage, even with subclassing and scribing. Currently it is not even close to the meta. Why have you decided to nerf already weak builds? You continue to add powerfull channeled skills, both updated "classes" (Dragonknight and Werewolf) have them. And such playstyle requires almost the same reaction/skill level as heavy attack builds, but you boost beam-like builds and nerf heavy attacks. I honestly don't understand your intentions.
