Well yes, lets look at the numbers, if the target have 1000 HP, at full health brand's passive would deal total of 8% (80), brands landed his Q with 200 magic damage (MR=0) at the first second this would deal 2% of the remaining 800 = 16, second tick would be (800-20-16)*0.02 = 15, 3rd = 15, 4th = 14, and the rest would deal the DOT version (3% of current) about 5 HP per second.

Total damage from this item would be 81 over 8 seconds with one of the best abilities that would work for.
