There's only 4 characters out of the whole lot that require this gear. If they made it easily accessible and/or cheaper to obtain they wouldn't have the power creep road block. The gear is designed to slow you down so everyone doesn't have massive GP rosters.. however if you want to speed along you must pay, hence the crystal purchases... Either way complaining that it's hard to obtain is not going to change anything, that's just validation to them that the business model is working as intended. Which by the way, it is.
I hate using the good ole "you didn't plan well enough" but... you didn't plan well enough. I used an entirely free to play obtained crystal stash and the double drop event to get all 200 pieces I needed for DR. Had them before his event even showed up. And no, I do not finish in the top of my arena shard or anything, at best I hover around 100 in both character arena and ship arena... I just did't spend anything knowing that I wanted DR the second time and wanted to get him close to G12 no matter what. So that was my primary focus.
