You know what, I think they'd do everyone a solid if they just retconned D3 out of everything.
I completely forgot what was the plot there, and I didn't even bother with reaper of soles.
You think you are being clever but one enhancement slot is permalocked for Fire Bolt and you are stuck with 4 defensives for end game. Again, before you press reply show some evidence that demonstrates otherwise.

There you go. One of the bog-standard endgame builds on icy veins. No Fire Bolt in Enchantment slot, just three "defensives".
Also, you are well aware only get to make this jab about "defenses" because both Teleport and Frost nova are clustered under defensive skills. Wow! Who's a clever boy.
Instead, they serve a variety of functions, depending how you specc. There's obviously the matter of mobility and crowd control, but most often they trigger an extra layer of damage
from their own effects and other synergies like the Tactician Glyph. These will also give a mana boost with Prodigy Aspect to keep the dps going.
Granted, Fire Bolt Enchantment opens up so many synergies, it's difficult to pass on and a glass cannon build probably needs all the defenses it can get... but you're not interested in
honestly discussing or even playing the game, so I won't be wasting my time.
