What we saw in D2 reveal could change and in this case I hope it will. The new subclass set up allows you to pick one of two perk clusters. Where in destiny 1 you could pick your four perks individually these new perk clusters have four perks pre chosen for you. I don't believe that these would be bad set ups , I just think that it takes away from character customization. In the first destiny I could run around with a bad but fun perk set up if I wanted to. Now I only get two choices and the perks available I might not like. Imagine being stuck with angel of light but you use that perk clusters because it has other perks that you want. TLDR:you only get two choices for perks and can get stuck with perks you don't like. Ps Datto mentions it in the video link
