I learned from day 1 of forsaken with acquiring MW from Spider at a cheap rate. Buy two MW a day and will only cost you a total of 30 legendary shards. I tend to use the higher light blue armours anyways while trying to get my light lvl up. Only use MW on my weapons that I like using in pve and pvp. I try not to get it in the habit of infusing every time I pick up a higher light gear. I do agree tho that something has to be done with infusing which cost way high for the advantage that you get🤔
