depends how much you gamble with your RP/Runes when using Bracer+Ring on like Goroth/Demonic/Sisters/Mistress/Harjatan/Desolate if your conservative with your HRW charge and wait till your at 25-30 RP to use HRW this change will hurt you, but if your liberal with your HRW use and do it at alike 60+RP this wont change anything for you.
I only mention those as all the other fights will force you to drop BoS due to a boss mechanic.
