If you guys want to get ahead of a meta that will eventually present itself, start figuring out how to gear around the default/auto attack skills in this game.
Every single one of them scales out of control, cost no mana, get free links at various levels (6 at level 90) and do crazy damage with levels. And, coincidentally, the attack based ones are pure phys and so get full benefit from leech.
To illustrate here are some links to some of them:
Conjure a circle of ritual inscriptions that last for a short duration. When the duration ends, spikes of bone erupt from enemies in the area, damaging them and potentially causing Bleeding.

Fire a burst of Chaos energy at the target.

Fire an arrow with your Bow.

This will be meta, and some streamer(s) will laugh about "how did nobody notice this! why is GGG putting this into the game?!"
