Honestly, surprises me some actions taken by SE. This one in particular, i just can see harmful potential, not a single benefit.
And im not saying about the advent of refractive crystals, but inserting it in unity content as well as an option to purchase it with accolades.
The correct way to implement those items would be adding them as coffer drop from incursion itself. Doing this, instead reducing the interest in incursion, would in fact increase, as incursion, besides capes, would be a gil farming place, and would incentivate high lv incursion (more hq coffer, more crystals, more cash).
Instead, adding it in unity not just drop interest of incursion, but also drop interest in unity (instead doing nms for maybe cash drops like mats, some vould prefer burning in fast, garanteed cash from crystals). Finally, its a change that totally favor... Botters, yeah. Casual player would nebver go out of his way to farm accolades, and the accolades gain rate is stupid, there is just no point in burning in crystals if you farm it like normal people, you will need them to do nms. Only people that can profit with such crystals that are stupdly overpriced (accolade-wise) are botters that swin in accolades/sparks/cp.
Seriously.
