A Warrior is only as good as their weapon.
Let’s get this out of the way, I want Titan’s Grip in Season of Discovery.
From a fantasy perspective, there’s nothing more defining or central to the Warrior class than its superior ability to wield weapons better than any other class. Titan’s Grip undoubtedly fulfills that fantasy.
”When everyone’s super, no one will be”
From a balance perspective, very reasonable widespread concern can easily be seen across the forums regarding Titan’s Grip. Titan’s Grip must be a level 60 rune, no exceptions, but that’s just the beginning. On top of this, TG could be like unto a legendary item. An incredibly rare drop (or multiple drops), a lengthy quest line, rare crafting materials, the works. Seeing a warrior w/ two 2H weapons could be like seeing someone with Thunderfury, Sulfuras, or Atiesh.
There’s significantly less concern about the balance/inclusion of Classic legendary weapons in PvP/PvE scenarios. It’s because they’re not everywhere, they’re hard earned.
I believe every class could have a rune or two like this. Something that amplifies class identity and personal achievement and isn’t at the expense of the rest of the community. By setting a high bar of achievement and dedication, the power level of TG becomes much more manageable. Adding the “Unique” property to certain 2H weapons, adjusting DPS modifiers, even altering how the rune interacts with 2H power levels in battlegrounds, open world PvP, and PvE.
Players get new ways to play, new things to do in the end game for every class, loot distribution stays safe and stable, the extra power is hard earned and not widespread, and the management of that power is much more easily regulated on the development side. Implementing TG is good for the game when done right!
