The reason why most null magic matnle recipes got more expensive and/or less effective because brawlers were able to get cheap mr items and be invincible against casters.

Now, with mantle being less effective, and negatron cloak being more expensive, MR is a stat you have to dedicate yourself to. If you're getting mr, you are sacrificing money for damage, making brawlers get less, and ensuring that tanks will be the only ones that bull shrug off spells.
