Technically you don't need the gear if you can overcome the obstacle without the additional IL otherwise suck it up buttercup. Honestly, it's your choice to do normal mode to squeeze in that extra IL and if you don't like it then maybe you don't need to push on savage as hard as you do? You are only tiring yourself out because you feel the need to obtain all the gear from the lockouts because you feel the need to complete savage as soon as possible, but honestly savage is still going to be there months from now and it's only going to be easier to gear which also means it's going to be easier to beat because you will have an easier time overcoming the IL for said content.
