You are not supposed to be able to have everything. You are suposed to make compromises. You get a fantastic stun, great ulti, sustain off ulti, good mag dots, very good spammable, room for ele drain, major mending, 50% projectile damage mitigation with snare removal...
The absence of a "viable" hot is nothing compared to magdens and magcro absence of a viable stun or nightblades absence of burst.
Mag dk is in a great spot right now when compared to those magica counter parts.
