You only lose only about 10-15 damage per activation if you start with 18 bonus ad (reds, quints, masteries), and this is something that the new passive effect should make up for. You lose 10 on odd levels, 15 on even, thanks to the way ranks work.

See pic for details.

Now as for how much the change from magic to physical damage is going to affect things, that depends on who you're up against and what kind of runes they're sporting.
