Rogues Combat Medic heals too much!

[3694]

The Rogues Combat Medic heals too much!
When you upgrade effective packs and good medicine it should heal 30% + heal over time (each pack).
But it heals 2x30% + heal over time (each pack).
2 packs = 120%hp + h.o.t. | 3 packs = 180%hp + h.o.t.

If you upgrade only 1 of them, then it heals as it should.
